It is more common in smoklated breast cancer journal articles discount clomiphene on line, or sessile growth that usually occurs as a ers and patients older than 60 years of age womens health education purchase clomiphene without a prescription. The solitary lesion menstrual vitamin deficiency discount clomiphene 25 mg online, although multiple lesions may also gingiva and alveolar mucosa are most frequently develop women's health center worcester ma buy clomiphene 25mg low price. It consists of numerous small projecinvolved women's health center queens blvd discount clomiphene online, followed by buccal mucosa and tongue menopause 14th street playhouse cheap clomiphene 50mg without a prescription. The tumor has a white or grayish first, which is referred to as the "sharp" variety, color and varies in size from several millimeters to consists of long, narrow, and white verrucous 1 or 2 cm in diameter. The second, which is referred to as the the palate and the tongue and less often on the "blunt" variety, consists of white verrucous probuccal mucosa, gingiva, and lips. The differential diagnosis includes verruca vulVerrucous hyperplasia is frequently associated garis, condyloma acuminatum, verruciform xanwith leukoplakia (53%), as well as verrucous carthoma, sialadenoma papilliferum, verrucous carcinoma (29%), and rarely squamous cell carcinoma, and focal dermal hypoplasia syndrome. The differential diagnosis should include proliferating verrucous leukoplakia, verrucous carTreatment is surgical excision. Benign Tumors Keratoacanthoma the differential diagnosis includes giant cell fibroma, lipoma, myxoma, peripheral ossifying fiKeratoacanthoma is a fairly common benign skin broma, neurofibroma, schwannoma, fibrous histumor that probably arises from the hair follicles. Clinically, it appears as a painless well-circumscribed dome or bud-shaped tumor of Treatment is surgical excision. The tumor begins as a small nodule that grows rapidly and, within 4 to 8 weeks, reaches its Giant Cell Fibroma full size. For a period of 1 to 2 months, it persists without change, and then it may undergo sponGiant cell fibroma is a fibrous lesion of the oral taneous regression over the next 5 to 10 weeks. The differential diagnosis should include basal and the differential diagnosis should include fibroma, squamous cell carcinomas and warty dysneurofibroma, papilloma, peripheral ossifying fikeratoma. Fibroma Fibroma is the most common benign tumor of the oral cavity and originates from the connective tissue. It is believed that the true fibroma is very rare and that most cases represent fibrous hyperplasia caused by chronic irritation. Clinically, the fibroma is a well-defined, firm, sessile or pedunculated tumor with a smooth surface of normal epithelium. It appears as an asymptomatic, single lesion usually under 1 cm in diameter, although in rare cases it may reach several centimeters. Benign Tumors Peripheral Ossifying Fibroma Soft-Tissue Osteoma Peripheral ossifying fibroma, or peripheral odonOsteomas are benign tumors that represent a protogenic fibroma, is a benign tumor that is located liferation of mature cancellous or compact bone. Osteomas are more common unknown, although it is believed that it derives between 30 and 50 years of age and have a prefrom the periodontal ligament. Clinically, it is a drome, oral soft tissue osteomas are, however, well-defined firm tumor, sessile or pedunculated, rare. Lesions have been described in the palate, covered by smooth normal epithelium. Usually the surface is ulcerated due to Clinically, soft-tissue osteoma appears as a mechanical trauma. The size varies from a few well-defined, asymptomatic hard tumor covered millimeters to 1 to 2 cm, and more than 50% of by thin and smooth normal epithelium. The differential diagnosis of soft tissue osteoma the differential diagnosis should include fibroma, includes torus palatinus, exostoses, and fibroma. The diagnosis is established by loma, pyogenic granuloma, pregnancy granuloma, histopathologic examination. Benign Tumors Lipoma Neurofibroma Lipoma is a benign tumor of adipose tissue relaNeurofibroma is a benign overgrowth of nerve tively rare in the oral cavity. It is more common tissue origin (Schwann cells, perineural cells, between 40 and 60 years of age and is usually endoneurium). It is relatively rare in the mouth located on the buccal mucosa, tongue, mucobucand may occur as a solitary or as multiple lesions cal fold, floor of the mouth, lips, and gingiva. Clinically, it usually tumor, pedunculated or sessile, varying in size appears as a painless well-defined pedunculated from a few millimeters to several centimeters of firm tumor, covered by normal epithelium. Neurofibromas vary in size from several epithelium is thin, with visible blood vessels. The lesion is soft on palpation and occasionally fluctuant and usually located on the buccal mucosa and palate, may be misdiagnosed as a cyst, especially when it followed by the alveolar ridge, floor of the mouth, is located in the deeper submucosal tissues. The differential diagnosis includes myxoma, fithe differential diagnosis includes schwannoma, broma, mucocele, and small dermoid cyst. It is extremely rare in the oral mucosa and most of the lesions represent myxoid degeneration of the connective tissue and not a true neoplasm. Clinically, the myxoma is a well-defined mobile tumor covered by normal epithelium and soft on palpation. It may appear at any age and is most frequent on the buccal mucosa, floor of the mouth, and palate. The differential diagnosis includes fibroma, lipoma, mucoceles, and focal mucinosis. Immunohistochemical markers are useful to distinguish nerve sheath myxomas from other oral myxoid lesions. Benign Tumors Schwannoma Leiomyoma Schwannoma, or neurilemoma, is a rare benign Leiomyoma is a rare benign tumor derived from tumor derived from the Schwann cells of the nerve smooth muscles. Clinically, it appears as a solitary wellsmooth muscles of blood vessel walls and from the circumscribed firm and sessile nodule, usually circumvallate papillae of the tongue. It is oma affects both sexes equally and usually persons painless, fairly firm on palpation, and varies in more than 30 years of age. The Schwannoma may occur at any age and is a slow-growing, painless, firm, and well-defined most commonly located on the tongue, followed tumor with normal or reddish color. Most frequently, it occurs on the tongue, followed by the buccal mucosa, palate, and lower lip. The differential diagnosis includes neurofibroma, fibroma, granular cell tumor, lipoma, leiomyoma, the differential diagnosis includes other benign traumatic neuroma, pleomorphic adenoma, and tumors of connective tissue origin and blood vesother salivary gland tumors. Traumatic Neuroma Traumatic neuroma or amputation neuroma is not a true neoplasm, but a hyperplasia of nerve fibers and surrounding tissues, after injury or transection of a nerve. Clinically, it appears as a small, usually movable tumor or nodule covered by normal mucosa. Traumatic neuroma is characterized by pain, particularly on palpation, and is often located close to the mental foramen, on the alveolar mucosa of edentulous areas, the lips, and the tongue. The differential diagnosis includes neurofibroma, schwannoma, foreign-body reaction, and salivary gland tumor. Benign Tumors Verruciform Xanthoma Benign Fibrous Histiocytoma Verruciform xanthoma is a rare benign tumor of Benign fibrous histiocytoma is a cellular tumor the oral cavity, of unknown cause and hisprimarily composed of histiocytes and fibroblasts togenesis, first described by Shafer in 1971. It represents a outstanding microscopic feature is the presence of localized reactive lesion rather than a true neolarge xanthoma or foam cells in the connective plasm. The tumor occurs more often on the skin of tissue papillae, which do not extend beyond the the neck region and very rarely on the oral epithelial rete peg extensions. Both sexes are affected, between 8 and between the 5th and 7th decades of life and seems 70 years old, and the size of the tumor ranges to have a slight predilection for females (female: between 0. Less cally, it appears as a painless, mobile, and firm often, it may be seen on the mucobuccal fold, tumor, covered by normal epithelium, which may palate, floor of the mouth, tongue, lips, and bucbe ulcerated. Clinically, it appears as a sessile, the differential diagnosis includes fibroma, slightly elevated, and well-defined lesion. It has a neurofibroma, schwannoma, lipoma, and granular cauliflower-like surface with normal or red-yelcell tumor. The diagnosis is established by the differential diagnosis includes papilloma, verhistopathologic criteria. Recent evidence indicates that the origin of the tumor may be the perineural Schwann cells rather than muscles. Clinically, it is a small, firm, well-defined asymptomatic nodule with whitish or normal color, which may be slightly elevated. In the oral cavity it is usually located on the dorsum and the lateral border of the tongue. The differential diagnosis should include rhabdomyoma, fibroma, neurofibroma, schwannoma, traumatic neuroma, congenital epulis of the newborn, and other benign mesenchymal tumors. This concept is supKlippel-Trenaunay-Weber syndrome, and the ported by the frequent presence of hemangiomas Rendu-Osler-Weber syndrome. On histologic criteria, two Laboratory test useful for the diagnosis is hismain types of hemangiomas are recognized: capiltopathologic examination. The biopsy has to be lary hemangioma, which consists of numerous taken very cautiously because of the danger of small capillaries and clinically appears as a flat red hemorrhage. Some congenital hemangiomas have been teristic clinical sign of the lesions is that on found to undergo spontaneous regression. Lymphangioma Cystic Hygroma Lymphangioma is a relatively common benign Cystic hygroma is a variety of lymphangioma that tumor of the oral cavity and, like hemangioma, it consists of large lymphatic sinuses and appears in is a developmental abnormality rather than a true infancy or early childhood. The great majority of the lesions diffuse soft swelling of the neck, extending to the appear during the first 3 years of life and show a submandibular or sublingual area and occasionally marked predilection for the head and neck region. It may cause esthetic or respiratory probby small soft elevated nodules that resemble small lems. Less often, it may be found on the lips, buccal mucosa, floor of the mouth and soft palate, but it is extremely rare on the gingiva. It is usually asymptomatic, but when it gets larger, it may cause pain and discomfort during speech, chewing, and swallowing, or macroglossia. Recurrent infection of the lesion is common and constitutes a serious problem. The differential diagnosis includes hemangioma, median rhomboid glossitis, lingual thyroid, and papillary hyperplasia of the palate. Papillary Syringadenoma the differential diagnosis includes lipoma, verof the Lower Lip ruciform xanthoma, myxoma, and fibroma. Histopathologic examination Papillary syringadenoma, or syringocystadenoma establishes the diagnosis. The tumor usually appears at birth or in early life Treatment is surgical excision. Clinically, it is characterized by a solitary well-defined plaque or nodule with a corrugated, slightly depressed surCutaneous Horn face. The lips Cutaneous horn is a clinical descriptive term repare an uncommon location of papillary syringresenting a prominent conical projection of coheadenoma, and sporadic cases have been recorded sive keratinized material, which usually occurs in. The lesion forms from cutaneous the differential diagnosis includes basal cell carkeratotic changes, such as seborrhoeic keratosis, cinoma, squamous cell carcinoma, keratoacanactinic keratosis, actinic cheilitis, warts, basal cell thoma, and other skin tumors. Clinically, cutaneous horns present as hard yellowish or whitish-brown straight or curved horn Treatment is surgical excision. The upper part of the face is the most common site of involvement, although Sebaceous Adenoma rarely cutaneous horns may be seen on the lower Sebaceous adenoma is a rare benign tumor of skin lip. The tumor growth (mucosal horn) whitish in color may very usually occurs as a solitary lesion on the face or rarely occur on the glans penis and intraorally scalp of elderly patients. Benign Tumors Freckles I ntramucosal Nevus Freckles are discrete brown macules, less than Pigmented cellular nevi are developmental mal0. They are pear during the first 3 years of life exclusively on collections of nevus cells in the epidermis, dermis, sun-exposed skin. Clinically, it is an asymptomatic, flat, or slightly Lentigo Simplex elevated spot or plaque of brown or brown-black Lentigo is a circumscribed brown spot of unknown color. It is usually located on the palate cause that is due to an increased number of epiand buccal mucosa and rarely on the gingiva and dermal melanocytes. Intramucosal nevi have little capacity for three varieties: lentigo simplex, lentigo solar, and malignant transformation. Lentigo simplex mainly appears the differential diagnosis includes other types of on the skin, nail beds, and rarely on the oral oral nevi, freckles, lentigo simplex, amalgam tatmucosa. It is not related to sun exposure and it too, hematoma, lentigo maligna, and malignant appears usually during childhood. The diagnosis is established by round flat spots of brown or dark brown color histopathologic examination. The differential diagnosis includes cellular nevi, Peutz-Jeghers syndrome, and freckles. However, surgical excision is recommended when the nevus is located at a site of chronic irritation or Laboratory test. Benign Tumors Junctional Nevus Blue Nevus Junctional nevus is the least frequent of oral nevi, Blue nevus is the second most frequent nevus of accounting for about 3 to 5. Histologically, it is characterized by the cells along the basal layer of the epithelium. Some presence of large numbers of elongated, slender, of these cells drop off into the underlying connecand melanin-containing melanocytes arranged in a tive tissue, showing junctional activity. The clinipattern parallel to the epithelium, in the middle cal features of junctional nevus are not pathoand lower parts of the lamina propria. Two types of blue nevus are black or brown flat or slightly elevated spots, recognized: the common type, which appears in which have a diameter of 0. Clinically, nevus has a significant capacity to undergo maligit appears as an asymptomatic, slightly elevated or nant transformation into melanoma. Clinically, flat spot or plaque, of oval or irregular shape any change in color, size, and texture of an oral brown or blue in color. It is frequently nevus should be regarded with suspicion and the located on the hard palate (60%) and rarely in possibility of malignant melanoma should not be other areas. The differential diagnosis includes the other types the differential diagnosis should include other of oral nevi, freckles, lentigo simplex, amalgam oral nevi, lentigo simplex, lentigo maligna, frecktattoo, normal pigmentation, lentigo maligna, and les, amalgam tattoo, hemangioma, pyogenic malignant melanoma. Compound Nevus Compound nevus is characterized by clusters of nevus cells located both in the epithelium and in the underlying connective tissue; therefore it has the characteristics of both intramucosal and functional nevus. Clinically, it appears as an asymptomatic slightly elevated or flat spot that has red-brown or blackbrown color, and the size varies from a few millimeters to 1 cm in diameter. The differential diagnosis should include other oral nevi, lentigo simplex, freckles, lentigo maligna, amalgam tattoo, and malignant melanoma. Nevus of Ota Lentigo Maligna Nevus of Ota, or oculodermal melanocytosis, is an Lentigo maligna, or melanotic freckle of Hutchinacquired blue or brown-gray macule characteristison, is a premalignant lesion of melanocytes.

Medical disorders and anaesthetic problems H Haemoglobinopathies (sickle cell Sickle cell disease disease) (see also Thalassaemia) A genetic abnormality of haemoglobin synthesis Normal haemoglobin (HbA) consists of a involving the substitution of valine for glutamic colourless protein, globin, which is made up acid at the sixth amino acid position in the beta from two alpha and two beta polypeptide chains, chain of the globin molecule. The haem radical is a frequently in blacks of African origin and in porphyrin structure, at the centre of which is a some Mediterranean races. Haemoglobinopathies associated with cell membrane is deformed by these molecular unstable haemoglobin. The process is complex and the precise mechanism of vasoocclusion is not known (Steinberg 1999). Sickle cell disease is associated with small Cooperative Study of Sickle Cell Disease and vessel occlusion and episodes of infarction in the Preoperative Transfusion in Sickle Cell affected organs. Reduced oxygen tension and al 1994), morbidity and mortality associated with acidosis cause sickling of red cells. The surgery and anaesthesia (Koshy et al 1995), and a 219 increased viscosity encourages stasis and trial of preoperative aggressive transfusion versus sludging, which in turn produces occlusion, conservative transfusion (Vichinksy et al 1995, ischaemia, and infarction. Papillary necrosis and haematuria Acute pain teams are increasingly being involved can develop as a result of sickling in the in the management of painful sickle cell crises. For elective procedures,the genotype should massive sudden pooling of red cells, be determined by haemoglobin electrophoresis. Medical disorders and anaesthetic problems H d) Haemolytic crises sometimes occur in marrow transplantation (Steinberg 1999). At association with glucose-6-phosphate present, the benefits have to be weighed against dehydrogenase deficiency following drug the possible complications (Cohen 1998). Infants less than 6 months old have high Anaesthetic problems percentages of HbF, therefore may not require transfusion. Sickling of red blood cells may be precipitated by hypoxia, acidosis, cold, and 8. Organ infarction, ischaemia, and recurrent episodes of chest pain, fever, with the further hypoxia, may result. An alternative progressive decreases in the saturation of theory is that rib infarction causes pleuritis and haemoglobin with oxygen. Despite statements techniques showed that these changes are further to the contrary, anaesthetics in those with sickle accentuated in a sickle cell crisis, possibly as a cell trait have not been entirely free from result of shunting (Singer et al 1989). Superior sagittal sinus thrombosis infarcts, have been reported in 17% of young occurred in a child following eye surgery (Dalal patients with sickle cell disease (Kinney et al et al 1974). Cholelithiasis is common, and reported and subsequent maternal death occurred during incidences vary from 4% to 55%, depending on Caesarean section (Anaesthetic Advisory the method of diagnosis.

A drying agent is essential, because of although initial resuscitation was successful, the excessive secretions, and sedatives are best patient died 2 weeks later (Gaitini et al 1998). It has been claimed that inhalation infiltration with myxomatous tissue around the inductions are difficult, and intravenous agents vocal cords, was found in one patient (Orliaguet are dangerous (Herrick & Rhine 1988). Venous access may be a problem (King et and should only be carried out by those al 1984). A nasal airway has been suggested as being obstruction, with oxygen desaturation and more effective than an oral one (Brown 1984), hypercarbia during sleep, has been reported and this can be left in place until the patient is (Ruckstein et al 1990). Lateral X-rays in two patients have shown failure and growth retardation (Stevens 1988). In that an oral airway pushes the epiglottis down a study of 21 patients, 50% had a clinical history and backwards to occlude the laryngeal inlet, of sleep apnoea and 90% had evidence of it whereas a nasal airway keeps it forward. Pulmonary oedema occurred secondary to Preoperative tracheostomy has been performed airway obstruction in a patient undergoing in patients with known failed intubation (Baines fibreoptic intubation (Wilder & Belani 1990). Delayed recovery from anaesthesia has nasopharyngeal tube has been described in a been reported in a 27-kg boy (Kreidstein et al patient with cardiac failure and episodes of 1994). A careful assessment of the airway, and patient, and the fact that laryngoscopy at the end possible intubation difficulties, is essential. Parents should be warned airway, both for routine airway management and of the increased risk of anaesthesia, and that as a back-up to failed intubation. Two experienced Moores et al (1996) suggest that the role of the anaesthetists should be present. Caesarean section has been reported antagonists as a precaution against acid aspiration under local anaesthetic infiltration (Gautam et al syndrome is recommended.

Trigeminal Nerve Schwannomas quired cholesteatomas, suggesting that intradural epidermoid Trigeminal nerve schwannomas initially present with cysts are also derived from cells of the first branchial groove. These tumors frequently involve both the middle and posterior fossa and a combined Nonvestibular schwannomas represent more than 95% approach may be necessary for resection. The primary Schwannomas of these cranial nerves produce symptoms treatment, similar to that for vestibular schwannoma, is based on their cranial nerve functions, thereby causing surgical resection. Facial nerve schwannomas most commonly occur at the Temporal bone hemangiomas involving the facial nerve. Similar to a vestibular schwannoma, a giomas with primary facial repair as the treatment of choice. The many faces of facial nerve symptoms such as facial spasm or weakness usually schwannoma. These include paragangliomas (glomus jugulare neoplasms), hemangiomas, and aneurysms. Paragangliomas lesions occur because of errors in embryogenesis that (Glomus Jugulare Neoplasms) allow vestigial structures to remain and grow during adult life. These neoplasms are slow growing and present toms are very similar to , if not indistinguishable from, initially with pulsatile tinnitus and conductive hearing those of vestibular schwannoma, and only imaging loss. The treatment is surgical, but total removal is more difParagangliomas cause irregular expansion of the jugular ficult than in vestibular schwannoma and is not always foramen, whereas lower cranial nerve schwannomas necessary. The rate of growth is unpredictable great vessels and allow for preoperative embolization of and patients may present with arachnoid cysts in the larger neoplasms.

The facial paresis occurs sooner with imaging, and become hypointense on T1-weighted imaghemangiomas than with facial nerve schwannomas. Therefore, the surgical geniculate ganglion, with surrounding smooth or irregular treatment of these lesions, if they become symptomatic, is bony enlargement of the fallopian canal. The obstruction of these air cells leads to allow characterization of these vascular lesions. Short-term tumor control and crystals and a foreign body reaction in the petrous apex. The differentiation is skull base chordomas occur at the clivus (sphenooccipital based primarily on imaging characteristics. Characteristics suggestive of intra-axial weighted images, marked gadolinium enhancement, and tumors include irregular and poorly defined brain hyperintense T2-weighted images. Unusual lesions of the main differential diagnosis of chordomas is chondthe cerebellopontine angle: a segmental approach. Hearing loss may very well be the preweighted images, and enhanced with gadolinium. The extent of treatment is based on since chondrosarcomas, unlike chordomas, do not stain the extent of the metastatic and primary disease and positively with epithelial tissue markers. Base of skull of treatment includes relieving symptoms of hydrocephchordomas in children and adolescents: a clinicopathologic alus or brainstem compression.

Understanding the bromas, Wishart-Gardner-Eldridge syndrome, neurinomafunction of merlin in tumor formation will lead to the tosis, and neurofibrosarcomatosis. The gene product rofibromatosis from those of a predominantly intracrais similar in sequence to a family of proteins the include nial subtype or central neurofibromatosis. Alteration in a new gene encoding a putative membrane-organizing protein causes neurofibromatosis type 2. A novel moesin-, ezrin-, radixin-like gene is a candidate for the neurofibromatosis 2 tumor suppressor. The loss of function of the merlin protein ever, cannot easily be categorized into these subtypes therefore could result in a loss of contact inhibition and and have many overlapping features. The hearing loss is usually proing meningiomas, malignant mesotheliomas, melanogressive and is associated with poor speech discriminamas, and breast carcinomas.

It is sis, facial hypesthesia, hydrocephalus, and progressive advisable for these patients to learn lip reading at an early tumor growth. The management priority should therefore be to maintain function even at the preservation of hearing, if technically possible, is far the expense of incomplete tumor removal, if that is preferable to hearing restoration. However, when both ears hear in an attempt to preserve hearing is more acceptable as a well, some divergence in opinion exists.

If the initial operation is successful in preserving option in patients in whom the cochlear nerve has been hearing, the surgical excision of the second tumor could be preserved. This brainstem encroachment requires removal, or the tumor problem may be overcome by either removing the magappears to be enlarging rapidly. Incomplete removal in an net from the receiver or by developing newer-generaonly-hearing ear has been recommended to preserve heartion implants without magnets. It is an alternate treatment option for the proneurophysiologist for cranial nerve monitoring. Spinal foundly deaf because cochlear implants cannot be used tumors and meningiomas are generally observed; signs of in this patient population. The Nucleus 22-channel growth, neurologic compromise, or clinical deterioration auditory brainstem implant design was first presented at usually lead to surgical intervention. Occasionally, a the Second International Symposium on Cochlear meningioma can be resected at the same time as another Implants in Iowa in 1989. The implantation of an auditory brainstem Stereotactic radiosurgery is a method of using ionizing implant can be carried out at the same time as tumor radiation to destroy a precisely defined area of intracraremoval. The technique combines a stereotactic delivnucleus complex is necessary, with a recommendation ery device with ionizing radiation. The radiation dose for intraoperative monitoring of the facial and glosin stereotactic radiosurgery is delivered by several presopharyngeal nerves. The evoked auditory brainstem potentials is important in radiation dose gradient is extremely sharp at the target determining the optimum placement of the auditory tissue, resulting in a sharply circumscribed area of highbrainstem implant on the cochlear nucleus complex. Cortical bone is thinned by medullary fibrous tissue that is vascular, compressible, and weak. Outer, middle, and inner ear structures are detailed and foraminal stenoses are identified. Histologically, there are interspersed regions of predominantly soft tissue or bone.

Though ectodermal derivatives are most prominent features womens health 4 week diet generic 100mg clomiphene visa, tissues of mesodermal and endodermal origin are also commonly present women's health center foothills calgary 50 mg clomiphene with visa. They are more common in prepubertal adolescents and young women under 20 years of age. G/A Malignant teratoma is a unilateral solid mass which on cut section shows characteristic variegated appearance revealing areas of haemorrhages, necrosis, tiny cysts and heterogeneous admixture of various tissue elements. M/E Parts of the tumour may show mature tissues, while most of it is composed of immature tissues having an embryonic appearance. Immature tissue elements may differentiate towards cartilage, bone, glandular structures, neural tissue etc, and are distributed in spindle-shaped myxoid or undifferentiated sarcoma cells. An important factor in grading and determining the prognosis of immature teratoma is the relative amount of immature neural tissue. Cut section of the tumour is grey-white to pink, lobulated, soft and feshy with foci of haemorrhages and necrosis. The tumour cells are arranged in diffuse sheets, islands and cords separated by scanty fbrous stroma. The tumour cells are uniform in appearance and large, with vesicular nuclei and clear cytoplasm rich in glycogen. The fbrous stroma generally contains lymphocytic infltrate and sometimes may have sarcoidlike granulomas. More often, endodermal sinus tumour is found in combination with other germ cell tumours rather than in pure form. M/E Like its testicular counterpart, the endodermal sinus tumour is characterised by the presence of papillary projections having a central blood vessel with perivascular layer of anaplastic embryonal germ cells. Such structures resemble the endodermal sinuses of the rat placenta (SchillerDuval body) from which the tumour derives its name. Ovarian choriocarcinoma is more malignant than that of placental origin and disseminates widely via bloodstream to the lungs, liver, bone, brain and kidneys. The group includes: pure granulosa cell tumours, pure thecomas, combination of granulosa-theca cell tumours and fbromas. These tumours invade locally but occasionally may have more aggressive and malignant behaviour. G/A Granulosa cell tumour is a small, solid, partly cystic and usually unilateral tumour. M/E the granulosa cells are arranged in a variety of patterns including microand macrofollicular, trabecular, bands and diffuse sheets. The microfollicular pattern is characterised by the presence of characteristic rosettelike structures, Call-Exner bodies, having central rounded pink mass surrounded by a circular row of granulosa cells. M/E Thecoma consists of spindle-shaped theca cells of the ovary admixed with variable amount of hyalinised collagen. The cytoplasm of theca cells is lipid-rich and vacuolated which reacts with lipid stains. Well-differentiated androblastoma composed almost entirely of Sertoli cells or Leydig cells forming well-defned tubules. Tumours with intermediate differentiation have a biphasic pattern with formation of solid sheets in which abortive tubules are present. Poorly-differentiated or sarcomatoid variety is composed of spindle cells resembling sarcoma with interspersed scanty Leydig cells. The term gynandroblastoma stands for combination of female (gyn) and male (andro). The examples of these tumours are: hilus cell tumours, adrenal rest tumours and luteomas. Metastasis may occur by lymphatic or haematogenous route but direct extension from adjacent organs. Bilaterality of the tumour is the most helpful clue to diagnosis of metastatic tumour. Most common primary sites from where metastases to the ovaries are encountered are: carcinomas of the breast, genital tract, gastrointestinal tract. The tumour is generally secondary to a gastric carcinoma but other primary sites where signet ring carcinomas occur. G/A Krukenberg tumour forms moderately large, rounded or kidneyshaped, frm, multinodular masses in both ovaries. Cut section shows greywhite to yellow, frm, feshy tumour and may have areas of haemorrhage and necrosis. M/E It is characterised by the presence of mucin-flled signet ring cells which may lie singly or in clusters. It is accompanied by cellular proliferation of ovarian stroma in a storiform pattern. The umbilical cord is about 50 cm long and contains two umbilical arteries and one umbilical vein attached at the foetal surface. The maternal portion of the placenta has irregular grooves dividing it into cotyledons which are composed of sheets of decidua basalis and remnants of blood vessels. The foetal portion of the placenta is composed of numerous functional units called chorionic villi and comprise the major part of placenta at term. The villous core is covered by an inner layer of cytotrophoblast and outer layer of syncytiotrophoblast. Hydatidiform mole is defned as an abnormal placenta characterised by 2 features: i) Enlarged, oedematous and hydropic change of the chorionic villi which become vesicular. Most workers consider hydatidiform mole as a benign tumour of placental tissue with potential for developing into choriocarcinoma, while some authors have described mole as a degenerative lesion though capable of neoplastic change. Clinically, the condition appears in 4th-5th month of gestation and is characterised by increase in uterine size, vaginal bleeding and often with symptoms of toxaemia. M/E the features are quite typical: i) Large, round, oedematous and acellular villi due to hydropic degeneration forming central cisterns. M/E Some of the villi show oedematous change while others are normal or even fbrotic. M/E the lesion is benign and identical to classic mole but has potential for haemorrhage. Approximately 50% of cases occur following hydatidiform mole, 25% following spontaneous abortion, 20% after an otherwise normal pregnancy, and 5% develop in an ectopic pregnancy. Clinically, the most common complaint is vaginal bleeding following a normal or abnormal pregnancy. Widespread haematogenous metastases are early and frequent in choriocarcinoma if not treated; these are found chiefy in the lungs, vagina, brain, liver and kidneys. Gestational choriocarcinoma and its metastases respond very well to chemotherapy while non-gestational choriocarcinoma is quite resistant to therapy and has worse prognosis. Krukenberg tumour is bilateral metastatic tumour from the following primary sites except: A. According to the Bethesda system, the squamous intraepithelial lesions for the grades of cervical cytology are: A. Genetic syndrome associated with increased risk of ovarian cancer includes all except: A. A 60 years old woman reports to physician for progressive fatigue, loss of appetite and malaise for the last 2 months. In a fully-developed non-lactating female breast, the epithelial component comprises less than 10% of the total volume but is more signifcant pathologically since majority of lesions pertain to this portion of the breast. The entire ductal-lobular epithelial system has bilayered lining: the inner epithelium with secretory and absorptive function, and an outer supporting myoepithelial lining, both having characteristic ultrastructure and immunoreactivity. The stromal tissue of the breast is present at 2 locations: intralobular and interlobular stroma. Bacteria such as staphylococci and streptococci gain entry into the breast by development of cracks and fssures in the nipple. Initially a localised area of acute infammation is produced which, if not effectively treated, may cause single or multiple breast abscesses. Tubercle bacilli reach the breast by haematogenous, lymphatic or direct spread, usually from the lungs or pleura. Pathologically, typical caseating tubercles with discharging sinuses through the surface of the breast are found. Silicone breast implants implanted on breast cancer patients after mastectomy or as breast augmentation cosmetic surgery may rupture or silicone may slowly leak into surrounding breast tissue. Idiopathic granulomatous mastitis is an uncommon form of reaction around lobules and ducts in the absence of any known etiology. Exact 508 pathogenesis is not known but probably it is a form of hypersensitivity reaction to luminal secretion of the breast epithelium during lactation. These are associated with periductal and interstitial chronic infammatory changes. The etiology of the condition remains unknown but it appears to begin with periductal infammation followed by destruction of the elastic tissue to cause ectasia and periductal fbrosis. G/A the condition appears as a single, poorly-defned indurated area in the breast with ropiness on the surface. Dilated ducts with either necrotic or atrophic lining by fattened epithelium and lumen containing granular, amorphous, pink debris and foam cells. Periductal and interstitial chronic infammation, chiefy lymphocytes, histiocytes with multinucleate histiocytic giant cells. Sometimes, plasma cells are present in impressive numbers and the condition is then termed plasma cell mastitis. Occasionally, there may be obliteration of the ducts by fbrous tissue and varying amount of infammation and is termed obliterative mastitis. M/E There is disruption of the regular pattern of lipocytes with formation of lipid-flled spaces surrounded by neutrophils, lymphocytes, plasma cells and histiocytes having foamy cytoplasm and frequent foreign body giant cell formation. The mammary duct is obstructed and dilated to form a thin-walled cyst flled with milky fuid. Its incidence has been reported to range from 10-20% in adult women, most often between 3rd and 5th decades of life, with dramatic decline in its incidence after menopause suggesting the role of oestrogen in its pathogenesis. As such, fbrocystic change of the female breast is a histologic entity characterised by following features: i) Cystic dilatation of terminal ducts. Presently, the spectrum of histologic changes is divided into two clinicopathologically relevant groups: A. The usual large cyst is rounded, translucent with bluish colour prior to opening (blue-dome cyst). Frequently, there is apocrine change or apocrine metaplasia in the lining of the cyst resembling the cells of apocrine sweat glands. Fibrosis There is increased fbrous stroma surrounding the cysts and variable degree of stromal lymphocytic infltrate. The latter condition, lobular hyperplasia, must be distinguished from adenosis (discussed separately) in which there is increase in the number of ductules or acini without any change in the number or type of cells lining them. M/E Epithelial hyperplasia is characterised by epithelial proliferation to more than its normal double layer. In general, ductal hyperplasia is termed as epithelial hyperplasia of usual type and may show various grades of epithelial proliferations (mild, moderate and atypical) as under, while lobular hyperplasia involving the ductules or acini is always atypical. Mild hyperplasia of ductal epithelium consists of at least three layers of cells above the basement membrane, present focally or evenly throughout the duct. Moderate and forid hyperplasia of ductal type is associated with tendency to fll the ductal lumen with proliferated epithelium. Such epithelial proliferations into the lumina of ducts may be focal, forming papillary epithelial projections called ductal papillomatosis, or may be more extensive, termed forid papillomatosis, or may fll the ductal lumen leaving only small fenestrations in it. Of all the ductal hyperplasias, atypical ductal hyperplasia is more ominous and has to be distinguished from intraductal carcinoma. The proliferated epithelial cells in the atypical ductal hyperplasia partially fll the duct lumen and produce irregular microglandular spaces or cribriform pattern. Atypical lobular hyperplasia is closely related to lobular carcinoma in situ but differs from the latter in having cytologically atypical cells only in half of the ductules or acini. The lesion may be present as diffusely scattered microscopic foci in the breast parenchyma, or may form an isolated palpable mass. G/A the lesion may be coexistent with other components of fbrocystic disease, or may form an isolated mass which has hard cartilage-like consistency, resembling an infltrating carcinoma. The histologic appearance may superfcially resemble infltrating carcinoma but differs from the latter in having maintained lobular pattern. Simple fbrocystic change or nonproliferative fbrocystic changes of fbrosis and cyst formation do not carry any increased risk of developing invasive breast cancer. Multifocal and bilateral proliferative changes in the breast pose increased risk to both the breasts equally. Within the group of proliferative fbrocystic changes,atypical hyperplasia in particular, carries 4 to 5 times increased risk to develop invasive breast cancer later. Since the male breast does not contain secretory lobules, the enlargement is mainly due to proliferation of ducts and increased periductal stroma. Such excessive oestrogenic activity in males is seen in young boys between 13 and 17 years of age (pubertal gynaecomastia), in men over 50 years (senescent gynaecomastia). G/A One or both the male breasts are enlarged having smooth glistening white tissue.
