Although serous tumors of low malignant potential (STLMP) of the ovary are relatively common, similar tumors of the fallopian tube are exceedingly rare. We report the case of an STLMP of the fallopian tube in a 31-year-old woman and review the literature.
Epithelial ovarian cancer (EOC) continues to be an academically challenging and clinically problematic disease. Even with recent advances, the overall 5-year survival is still 31% to 42% in various studies. Deaths from EOC outnumber those due to cervical, vulvar, and endometrial carcinomas combined. Screening for EOC has shown limited success in early detection. The Pap smear is not a dependable tool in EOC screening, though at times it can be the first evidence of ovarian disease. We report a case of EOC that was diagnosed during evaluation of an abnormal Pap smear. On completion of evaluation, stage IIIA endometrioid-type adenocarcinoma of the ovary was diagnosed. Occult EOC should be considered in patients with abnormal findings on cervical cytology after cervical and uterine carcinomas are ruled out.
We describe two rare cervical tumors having morphologic features closely resembling those of the nasopharyngeal lymphoepithelioma. This entity has historically been classified as a subtype of squamous cell carcinoma, but after reviewing the literature and the two cases presented here, we propose that this tumor is a distinct carcinoma of the cervix that differs from squamous cell carcinoma in that it carries a more favorable prognosis, typically affects a younger population of women, is more prevalent in noncaucasian populations (especially those of Asian descent), and lacks a clearly defined association with infection due to human papilloma virus (HPV).
This case report describes a 31-year-old woman at 8 weeks' gestation with large arteriovenous malformation of the uterus involving bilateral uterine and ovarian arteries. She had a history of multiple pregnancy losses, as well as spontaneous copious vaginal hemorrhage. The patient underwent an embolization procedure followed by total abdominal hysterectomy and bilateral salpingo-oophorectomy. The uterus was very small (30 g) despite its gravid status, and the overall microscopic findings indicated Müllerian system hypoplasia in addition to vascular malformation.
Leiomyomatosis peritonealis disseminata (LPD) is an exceedingly rare, usually benign condition that clinically simulates a disseminated malignancy. It occurs predominantly in women of childbearing age. Approximately 50 cases of LPD have been described in the literature with 2 cases reported to have progressed into aggressive leiomyosarcomas. Excessive hormonal stimulation appears to correlate with LPD development since it is commonly associated with pregnancy. Conservative treatment with long-term follow-up is recommended because of LPD's generally indolent clinical course. We report 5 cases of LPD with a review of the literature.
BACKGROUND: Basal cell carcinoma is the most common malignant tumor of the skin, with approximately 400,000 new cases yearly in the United States. Basal cell carcinomas account for 2-3% of all vulvar malignancies. CASES: Four patients presented in the eighth and ninth decades of life (70, 78, 87 and 89 years). Seventy-five percent of patients had a unifocal lesion. Cases 3 or 4 presented with recurrent lesions at 5 and 10 years, respectively. All patients were treated with wide local excision. Surgical margins were free of disease. None of the patients had lymph nodes suspicious for malignancy. CONCLUSION: Basal cell carcinoma can present as a unifocal or multifocal lesion. The lesions are usually located on the labia majora. Patients are frequently diagnosed with basal cell carcinoma of the vulva in the eighth and ninth decades of life. Treatment consists of wide local excision. Although 50% of these cases recurred, the lesions were reexcised, with wide local resection. No metastatic lesions were identified in any of the patients.

We report a case of basal cell carcinoma arising in a previously radiated field after treatment of cervical cancer. Our search of the literature yielded no other case of basal cell carcinoma due to irradiation for cervical carcinoma.
This report describes the case of a 29-year-old Nigerian woman with dracunculosis presenting as an adnexal mass. The patient had a history of two second-trimester spontaneous abortions for which she was being evaluated. During the evaluation, she was found to have multiple uterine leiomyomas and a calcified left adnexal mass by pelvic ultrasound and radiography. At laparotomy, the calcified mass was excised from the left broad ligament, and a myomectomy was performed. Histologic examination revealed a calcified, coiled guinea worm embedded in the fibrous tissue of the broad ligament. Only one other case of calcified guinea worm in the broad ligament has been reported in the literature.
Primary adenocarcinoma of the vulva, arising in continuity with the epidermis and unrelated to the underlying mucus glands, is a distinctly uncommon neoplasm. The origin of such an unusual tumor, although attributed to cloacal remnants, remains speculative. We describe two patients with this rare lesion. No other primary tumor was found in either of the two after a thorough investigation. One patient was treated with radical vulvectomy and was free of disease for 10 years, until her death from unrelated causes. The second patient was treated with wide local excision and was free of disease four years postoperatively. Our experience indicates the need to recognize this tumor as a primary and not metastatic neoplasm of the vulva. We also noticed that in both cases, despite its histologic malignancy and ulceration, the tumor was superficial in its extent and without any tendency for deeper invasion. It can therefore be treated effectively with wide local excision, thus eliminating the need for radical vulvectomy.
A case of primary carcinoma of the fallopian tube with coexistent tuberculosis has been presented, and previously reported cases in the literature reviewed. These cases represent a rare occurrence where the diagnosis might be missed without a thorough pathologic evaluation. Clinicians should maintain an index of suspicion for fallopian tube carcinoma in perimenopausal or postmenopausal women with menometrorrhagia who fail to respond to hormonal therapy and a D and C. The finding of a tuboovarian abscess in a postmenopausal woman should also cause concern for tubal carcinoma, as it is usually a disease of menarcheal women. Similarly, a possibility of granulomatous salpingitis should always be borne in mind in the differential diagnosis of inflammatory diseases of the fallopian tube.
Twenty-five cases of metastatic carcinoma of the umbilicus in women diagnosed and treated at Emory University Hospitals from 1973 to 1989 were reviewed, as were all previously reported cases in the English language literature. In our series, overall survival was greatest in patients treated with aggressive surgery and chemotherapy, compared with patients receiving no therapy or those treated with either surgery or adjunctive therapy alone. Individual survival was enhanced when the primary tumor site was of ovarian origin.
We have presented a case of paratesticular myxoma and have described the clinical history, findings on light microscopy and immunohistochemistry, and possible pathogenesis. Although primary paratesticular myxoma is a rare lesion, it should be considered in the differential diagnosis of intrascrotal mesenchymal tumors.
Granular cell tumor (GCT), although nearly ubiquitous, is seen infrequently in the vulva. A review of the surgical pathology files from Grady Memorial Hospital, Atlanta, Georgia, from 1983 through 1987 identified eight cases of vulvar GCT. Five of the eight patients had more than one skin and soft tissue lesion. Two of the five had biopsy-proven multicentric GCT with a unique clinical course. One of the patients was a 32-year-old woman with multiple vulvar, lingual, laryngeal, bronchial and pulmonary GCT, necessitating multiple excisions and ultimately pneumonectomy. The second patient had multiple GCTs in the vulva and inguinal area and finally in both lungs, resulting in her death at age 39. No dependable microscopic features could be identified to distinguish benign GCT from its more aggressive variant. However, Feulgen DNA histomorphometry demonstrated aneuploidy in the patient with apparent lung metastases, whereas the tumors from patients with a benign course as well as from the patient with multiorgan involvement were diploid. In three of five patients who could be interviewed there was a history of soft tissue tumors in members of the family. The multifocal nature and possible familial component of GCT need to be explored further.
Vulvar self-examination was used to facilitate early diagnosis and treatment of vulvar neoplasia in eight patients. Five of them were found to have invasive squamous cell carcinoma of the vulva, two had carcinoma in situ, and one had a vulva melanoma. All eight patients benefited from early diagnosis, which allowed definitive treatment and vulvar conservation.
Unilateral tubal twin pregnancy is exceedingly rare: only 91 cases have been reported in the English literature to date. Two additional such cases are described.
A ten-year review (1973-1983) revealed 13 cases of documented granuloma inguinale at Grady Memorial Hospital, Atlanta. The patients' ages ranged from 17 to 77, with the majority in their early 20s. The initial presentation of granuloma inguinale included large, fungating labial ulcers, labial swelling, vaginal discharge, rectovaginal fistulae and hematuria. Common presumptive diagnoses included carcinoma, herpes, syphilis and granuloma inguinale. The final diagnosis was made with cytology and/or tissue examination with the help of special stains to demonstrate the causative organism, Calymmatobacterium granulomatis. Granuloma inguinale is rare and difficult to diagnose, but with physician awareness, cytology and biopsy, it should not be missed.
The histopathology of eight cases of sporadic ileocaecal tuberculosis is described with particular reference to caecal lymphoid tissue. Adjacent to areas of ulceration in all cases there was an increase in lymphoglandular complexes (LGC) and proliferation of paravascular lymphoid aggregates deeper in the gut wall. Early and fully-developed granulomas were present in locations comparable to LGC and lymphoid aggregates. Immunocytochemical staining of paraffin sections with monoclonal antibodies UCHL1 (T-lymphocyte membrane antigen) and LN-1, LN-2 and LN-3 (B-lymphocyte and Ia antigens) showed that central cells in LGC and lymphoid aggregates stained like follicular centre B-lymphocytes. Both LGC and lymphoid aggregates had a distinct peripheral rim of cells staining as T-lymphocytes, but LN-2 and LN-3 also stained scattered peripheral cells, some of which were recognizable as interdigitating reticulum cells. Most lymphocytes within and around granulomas stained as T-lymphocytes. In lymph nodes, granulomas appeared to occur first at the periphery of, and later to efface, cortical follicles. Lymph node compartments showed the expected T- and B-zonation, and lymphocytes associated with granulomas stained as in caecal granulomas. Our observations suggest that LGC are sites of mycobacterial antigen sampling, of T-lymphocyte and macrophage activation, and of (potential) granuloma formation in ileocaecal tuberculosis. Lymphoid aggregates deeper in the gut wall probably subserve a similar function during extension of the lesion. The location of both LGC and lymphoid aggregates beside lymphatics is suited to the transfer of their cellular constituents throughout the gut and to regional lymph nodes.
