1/607. Vaginal epithelioid angiosarcoma.

    A case of epithelioid angiosarcoma of the vagina is described. Only five cases of angiosarcoma at this site have been reported, three of which followed radiotherapy for other gynaecological malignancies. None is described as an epithelioid angiosarcoma, an unusual and recently described variant which is readily confused with carcinoma. This is thought to be the first reported epithelioid angiosarcoma at this site and highlights the difficulties in diagnosis. ( info)

2/607. Borderline malignant change in recurrent mullerian papilloma of the vagina.

    Malignant change occurred in a benign, recurrent vaginal mullerian polyp. The patient, a 49 year old woman with cerebral palsy, presented with a polypoid mass in the vagina. At four years of age she had presented with a haemorrhagic polyp, and over the following years she had recurrent irregular bleeding and regrowth of the polypoidal mass, requiring a total of 10 operations to excise the polyp. Histological examination of the specimen showed typical mullerian features with tubal, endometrioid, and endocervical cell types. There were significantly abnormal nuclei, indicating low grade or borderline malignancy. review of previous biopsies showed similar mullerian features but no atypia. This is the first reported case of borderline malignant change in a previously benign recurrent mullerian papilloma of the vagina. Definitive radical surgery or radiotherapy is contraindicated in this patient and she remains under follow up. ( info)

3/607. Stromal sarcoma arising on endometriosis. A clinicopathological and immunohistochemical study of 4 cases.

    The development of stromal sarcomas on the foci of endometriosis is extremely rare and the differential diagnosis from other tumors of myogenic, vascular, hemopoietic or epithelial origin may present great diagnostic difficulties. We investigated the clinicopathological and immunohistochemical characteristics of 4 cases of endometrial stromal sarcoma that developed on endometriotic foci of the uterus, vagina and omentum. Thye were classed as high grade (1/4) or low grade (3/4) malignant potential tumors, according to their mitotic activity. Immunohistochemically these tumors gave a positive reaction to vimentin, but were negative to desmin, smooth muscle actin, factor viii, EMA and LCA. These characteristics permit their identification and a proper therapeutic approach. ( info)

4/607. Abnormal uterine bleeding as a presenting sign of metastases to the uterine corpus, cervix and vagina in a breast cancer patient on tamoxifen therapy.

    Metastases to the female genital tract from extragenital cancers are uncommon. The ovaries are most often affected with the breast and gastrointestinal tract being the most common sites of the primary malignancy. Metastases to the uterus from extragenital cancers are significantly rarer than metastases to the ovaries and in the majority of cases the ovaries are also involved. A case of metastases restricted to the uterine corpus, cervix and vagina from breast carcinoma, without involvement of the ovaries, is described. The patient who had been on tamoxifen therapy presented with postmenopausal bleeding. The diagnosis of uterine metastases was established during endometrial ablation and confirmed by total abdominal hysterectomy and bilateral salpingo-oophorectomy. This case illustrates that abnormal uterine bleeding in a breast cancer patient, regardless of whether she is receiving or not receiving tamoxifen, should always alert the physician to consider the possibility of uterine metastases from breast carcinoma.

5/607. Latent vaginal choriocarcinoma in a postmenopausal woman.

    A 50-year-old Japanese female with choriocarcinoma showed three unusual features: the primary tumor developed in the vagina ectopically without uterine lesion; the first symptoms of atypical vaginal bleeding and coughing occurred 23 years after the last pregnancy; and the tumor appeared during postmenopause. The possible mechanisms for the ectopic location and latency are discussed. ( info)

6/607. Urothelial carcinoma of the vagina six years following cystectomy for invasive cancer. A case report.

    A 74-year-old woman presented with vaginal spotting secondary to transitional cell carcinoma six years following cystectomy for invasive, yet localized, transitional cell carcinoma of the bladder. This represents primary, not metastatic, tumor of the vagina. ( info)

7/607. Primary non-Hodgkin's lymphoma and malakoplakia of the vagina: a case report.

    The vagina is a rare site for both primary non-Hodgkin's lymphoma and malakoplakia. We report a case of concurrent diffuse large B-cell lymphoma and malakoplakia of the vagina in a 67-year-old woman presenting with a vaginal discharge and a vaginal mass. The patient had two biopsy specimens reported as showing malakoplakia only, followed by a third biopsy specimen 10 months later which was diagnosed as diffuse large B-cell lymphoma. review of the first two biopsy specimens showed areas of histiocytes with Michaelis-Gutman bodies merging with areas of cells with slightly larger nuclei and more amphophilic cytoplasm. immunohistochemistry for the B-cell marker L-26 (CD20) and polymerase chain reaction analysis of the immunoglobulin heavy chain gene were helpful in retrospectively distinguishing the population of diffuse large B-cell lymphoma from the areas of malakoplakia. The third biopsy specimen showed sheets of large atypical lymphoid cells characteristic of a large cell lymphoma. Malakoplakia has been described in association with a variety of cancers, and this is only the second report of malakoplakia associated with non-Hodgkin's lymphoma. Considering the rarity of these two entities in the vagina, it is unlikely that the association in this case is coincidental, raising the possibilities of an unusual reaction to the presence of lymphoma or a common pathogenesis such as underlying chronic inflammation. Epstein-Barr virus dna was detected in the second biopsy specimen, suggesting a possible role in the pathogenesis of this lymphoma. ( info)

8/607. MR imaging of non-squamous vaginal tumors.

    We reviewed the MR images and pathologic findings of five cases of primary vaginal neoplasms of non-squamous origin. Histologic types consisted one case each of adenocarcinoma, adenosarcoma, melanoma, lymphoma, and neurilemoma. magnetic resonance imaging was found useful for evaluating the type and the extension of vaginal tumors.

9/607. Primary squamous cell carcinoma in a patient with vaginal agenesis.

    BACKGROUND: The development of a carcinoma in a neovagina constructed in patients with congenital vaginal agenesis is rare. CASE: To our knowledge, this is the first report of a squamous cell carcinoma developing in a neovagina that had been constructed by a simple cleavage technique without tissue transplantation. The latency period between reconstruction and tumor diagnosis was 20 years, during which the patient regularly used a prosthesis. The most important observation during this time was the repeated formation of granulation tissue and chronic inflammatory pseudopolyps in the neovagina, which were removed by cauterization. Despite pre- and intraoperative irradiation and radical surgery followed by chemotherapy, the prognosis is poor. CONCLUSION: patients with neovaginas, whatever the construction technique, need to be followed up regularly, as mechanical irritation from a prosthesis can add to other cancer risk factors, such as viral infection. Furthermore, the absence of transplanted tissue does not seem to protect from the risk. ( info)

10/607. choriocarcinoma co-existent with an intact pregnancy: case report and review of the literature.

    A patient presenting with antepartum haemorrhage due to a vaginal metastasis of choriocarcinoma is reported. Following delivery she was successfully treated with chemotherapy and surgery. This report details this unusual presentation and reviews the literature on this rare condition. ( info)
