A Fig. 6.24 Yolk sac tumour. A The tumour has a labryinthine pattern with occasional Schiller-Duvall bodies. B Papillary cores and labryinthine structures are lined by primitive cuboidal cells with cytoplasmic vacuolization and rare hyaline globules. B variants have a biphasic composition with areas similar to common blue naevus admixed with round nodules. The cells are arranged in nests and short fascicles with a whorled pattern and are plump and spindle-shaped with oval bland nuclei and pale cytoplasm. Differential diagnosis The common variant should not pose a diagnostic problem. The cellular variant may cause confusion with melanoma and smooth muscle tumours. Nuclear atypia and numerous mitotic figures would favour melanoma. Well defined interlacing fascicles, large thick-walled blood vessels, immunohistochemical positivity for muscle markers and negativity for S-100 protein should assist in making the diagnosis of a smooth muscle tumour. Melanocytic naevus Definition Melanocytic nevi are defined as proliferation of nests of naevus cells. Clinical features Melanocytic nevi of the vagina are thought to be similar to their counterparts in the skin {1539}. Yolk sac tumour Definition A primitive malignant germ cell tumour characterized by a variety of distinctive histological patterns, some of which recapitulate phases in the development of the normal yolk sac. ICD-O code 9071/3 Synonym Endodermal sinus tumour. Clinical features Patients are usually under 3 years of age. Vaginal bleeding and discharge are the most common symptoms. Serum levels of alpha-fetoprotein may be elevated. A polypoid friable mass is seen on clinical examination with a mean size of 3 cm. Histopathology Vaginal cases resemble their ovarian counterparts. Differential diagnosis Although sarcoma botryoides may be simulated clinically, the histological features resolve any confusion. Clear cell and endometrioid carcinomas may create difficulty in histological separation. Prognosis and predictive factors Combined surgery and chemotherapy may provide a favourable outcome. A disease-free survival of up to 23 years is possible {557}. Peripheral primitive neuroectodermal tumour / Ewing tumour Definition Tumours of uncertain lineage within the small round blue cell family of tumours. ICD-O code Peripheral primitive neuroectodermal tumour / 9364/3 Ewing tumour 9260/3 Clinical features Peripheral primitive neuro e c t o d e rm a l tumour/Ewing tumour (PNET/ET) is rare within the vagina {3002}. A reported case occurred in a 35-year-old woman who presented with a vaginal mass. Histopathology Histological features are similar to PNET/ET in non-vaginal sites. Typically, PNET/ET grows as a diffuse sheet of uniform small cells with scant pale cytoplasm and an intermediate to high nuclear to cytoplasmic ratio. The nuclei are round with evenly dispersed chromatin. Mitotic figures may be numerous, and rosettes may be seen. Immunoprofile Expression of CD99 would be expected in almost all cases. Differential diagnosis PNET/ET should not be mistaken for rhabdomyosarcoma, non-Hodgkin lymphoma (NHL), melanoma, small cell carcinoma or endometrial stromal sarcoma because of differences in prognosis and treatment. A broad immunohistochemical panel and, if need be, molecular studies, performed on paraffin-embedded tissue should assist in making the correct diagnosis. Molecular genetics Identification of the EWS/FLI1 fusion transcript derived from the t(11;22)(q24;q12) c h romosomal translocation by the Melanotic, neuroectodermal, lymphoid and secondary tumours 309
Fig. 6.25 Peripheral primitive neuroectodermal tumour. Note the sheets of small to medium sized cells with round, pale nuclei, minimal cytoplasm and high nuclear to cytoplasmic ratios. reverse transcriptase-polymerase chain reaction and Southern blot hybridization would confirm the diagnosis. Prognosis and predictive factors The experience with PNET/ET of the vagina is limited, but patients with localized tumours in soft tissue sites can potentially be cured with a combination of surgery, chemotherapy and radiation therapy. Dermoid cyst Definition A cystic tumour composed of more than one germ cell layer in which all elements are mature. ICD-O code Dermoid cyst 9084/0 Mature cystic teratoma 9080/0 Synonym Mature cystic teratoma. Macroscopy and histopathology These resemble the same tumour in the ovary. Adenomatoid tumour ICD-O code 9054/0 A single case occurring in a 47-year-old woman has been reported {1697}. Lymphoid and haematopoetic tumours Definition Tumours of the lymphoid and haematopoetic systems as well as secondary tumours of the vagina. Lymphoma Definition Tumours with lymphoid diff e re n t i a t i o n arising as either primary (localized) or secondary (disseminated) disease. Clinical features Lymphomas of the vagina are predominantly of the non-Hodgkin’s type {3001}. Patients with primary NHL have a mean age of 42 years, usually present with vaginal bleeding and have a mass on clinical examination. Patients with secondary NHL have a mean age of 65 years, present with vaginal bleeding and usually have a history of NHL. Histopathology Almost all NHLs primary in the vagina a re diffuse large B-cell lymphomas Table 6.03 Immunohistochemical and cytogenetic profile of various small cell tumours of the vagina.* Immunohistochemical Peripheral primitive Rhabdomyosarcoma B-cell Melanoma Small cell Endometrial or molecular markers neuroectodermal non-Hodgkin carcinoma stromal tumour/Ewing tumour lymphoma sarcoma Cytokeratin +/- +/- - - + +/- Muscle specific actin/ desmin - + - - - +/- Chromogranin/ synaptophysin +/- - - - +/- - S-100 protein +/- - - + - - HMB-45 - - - + - - Leukocyte common antigen/ CD20 - - + - - - CD10 - - +/- - - + CD99 + +/- +/- - - - t(11;22) + - - - - - t(2;13)/ t(1;13) - +/- - - - - Monoclonal immunoglobulin heavy chain gene - - +/- - - - rearrangement Key: +/-, variable rate of positivity; *, Not all markers have been thoroughly tested for each tumour, but expected results are listed. 310 Tumours of the vagina
