The accuracy of endometrial Pipelle sampling with and without sonographic measurement of endometrial thickness.

OBJECTIVE: To evaluate the accuracy of Pipelle endometrial sampling with and without sonographic measurement of endometrial thickness. METHODS: We studied prospectively 176 consecutive patients (23% after and 77% before menopause) scheduled for D&C. Sonographic measurement of the endometrium and endometrial biopsy with the Pipelle were performed before the curettage. RESULTS: In 159 cases (90%), the endometrial histologic results of curettage agreed with those of the Pipelle biopsy. All three cases of endometrial cancer were identified by Pipelle aspiration. In seven cases (4%), the Pipelle aspiration failed to detect hyperplasia. Sonographic endometrial thickness of more than 5 mm slightly increased the sensitivity and slightly decreased the specificity of Pipelle aspiration from 82 to 92% and from 99 to 96%, respectively. In postmenopausal patients admitted for bleeding, the sensitivity and specificity reached 100%. CONCLUSIONS: Our data suggest that normal Pipelle aspirates in premenopausal patients with abnormal uterine bleeding are highly accurate. In postmenopausal patients with sonographic endometrial thickness of 5 mm or less, the accuracy reached 100%.

Unsuspected involvement of the female genitalia in pemphigus vulgaris.

A 56-year-old woman had erosions due to pemphigus vulgaris in the inner thighs and perineum. The cutaneous lesions cleared following intramuscular gold therapy. However, because of complaints of dyspareunia, a colposcopic examination was performed and involvement of the cervix was demonstrated. The need for a vaginal examination in the monitoring of pemphigus vulgaris is emphasized.

Leiomyosarcoma of the bladder - ultrasonographic features.

We present a case in which the evaluation of a bladder mass revealed a leiomyosarcoma of the bladder. The ultrasonographic appearance of this tumor is described for the first time. Leiomyosarcoma of the bladder, although rare, should be considered in the differential diagnosis of pelvic masses.

Persistent gestational trophoblastic disease following evacuation of a tetraploid partial hydatidiform mole.

A 31-year-old woman at 11 weeks gestation with ultrasonographic demonstration of partial mole had markedly elevated serum bHCG levels (458,000 mIU/ml). The patient underwent a vacuum curettage with pathological confirmation of the diagnosis, and cytogenetic analysis revealed a tetraploid karyotype (92,XXXX). The patient developed persistent gestational trophoblastic disease and was successfully treated with two courses of actinomycin D. Persistent trophoblastic disease after evacuation of a tetraploid partial mole was not reported previously.

Aggressive angiomyxoma of the vulva.

A case of aggressive angiomyxoma (AAM) of the vulva is presented. The tumor presented as a slowly growing polypoid mass in the right labium minus near the clitoris. The tumor was treated by wide local excision. The microscopic appearance was that of spindle-shaped neoplastic cells widely separated by a loose myxoid stroma rich in collagen fibers, hyaluronic acid, and prominent irregular-shaped blood vessels. Aggressive angiomyxoma of the vulva must be distinguished from the more common benign and malignant myxoid tumors including myxoma, myxoid liposarcoma, myxoid variant of malignant fibrous histiocytoma, sarcoma botryoides, nerve sheath myxoma, and other soft tissue tumors with secondary myxoid changes. Local recurrence of AAM may be avoided by wide local excision.

Spontaneous ovarian hyperstimulation syndrome concomitant with spontaneous pregnancy in a woman with polycystic ovary disease.

Ovarian hyperstimulation syndrome has been described after treatment with exogenous gonadotropins, clomiphene citrate, and gonadotropin-releasing hormone. Spontaneous ovarian hyperstimulation syndrome has not been described before, except in association with hypothyroidism. We report on a case associated with spontaneous pregnancy, occurring in a woman with polycystic ovary disease.

Pneumothorax following induction chemotherapy in patients with lung metastases: a case report and literature review.

A 29-year-old patient presented with bilateral pulmonary lesions following surgery for recurrent placental site trophoblastic tumor (PSTT). On day seven after institution of the 'EMA' regimen (etoposide, medium dose methotrexate with folinic acid rescue and actinomycin-D), complete pneumothorax occurred. Closed-system air drainage brought only transient lung expansion and subsequent talc pleurodesis was needed. During follow-up, complete regression of lung metastases was observed. A literature survey of post-chemotherapy pneumothorax in patients with lung metastases disclosed fourteen hitherto reported cases. Including the present PSTT case, non-epithelial gynecologic malignancy (3 patients) ranks second to osteogenic sarcoma (6 cases) with regard to the primary tumor involved.

Malignant fibrous histiocytoma of the vagina and vulva successfully treated by combined chemotherapy and radiotherapy.

Combined vaginal and vulvar malignant fibrous histiocytoma has not been reported previously. Radical vulvectomy with node dissection is the currently recommended therapy for a vulvar lesion of this type. We present a case with complete tumor regression after combined chemotherapy and radiotherapy. The surgical approach in our patient was inappropriate due to advanced disease. Follow-up examinations for 6 years after initiation of therapy showed no evidence of local recurrence or distant metastasis. Chemotherapy followed by radiotherapy should be considered as an alternative to surgery in patients with advanced vaginal and vulvar involvement and in patients in whom complex medical problems preclude extensive surgical procedures.

Dysplastic vulvar nevi.

Of several pigmented vulvar lesions, the dysplastic nevus, a know precursor of malignant melanoma, has been described only twice. Focusing on pigmented vulvar lesions, 18 were excised among approximately 500 unselected parturients. Three lesions showed clinical and histologic characteristics of a dysplastic nevus. The patients with a dysplastic vulvar nevus were 21, 27, and 30 years old, respectively; all three had multiple torso and limb nevi and two had anamnestic features of the dysplastic nevus syndrome. Only one was aware of her vulvar lesion. All dysplastic nevi were brown or black and were larger than 5 mm in diameter. Our cases suggest that dysplastic vulvar nevi may be more frequent than previously thought. We suggest that the puerperium is a suitable time for a definite histologic diagnosis of large-size lesions with variegated pigmentary patterns and irregular borders that occur on the vulvar skin. Likewise, in other patients with suspected dysplastic vulvar nevi, excisional biopsy is recommended.

Ovarian mucinous cystadenoma with leiomyomatous mural nodule.

A case of an ovarian mucinous cystadenoma with a leiomyomatous mural nodule is described. The diagnosis was confirmed by immunohistochemical methods. This is the first report of a mural nodule of leiomyomatous nature, thus widening the histologic spectrum that may be encountered in these lesions.

Solitary thick intra-uterine membranes not associated with the amniotic band syndrome; three case reports.

Three cases in which a single intra-uterine membrane with a free and thickened edge was identified by ultrasound antenatally are presented. The bands turned out to be thickenings of the fetal membranes. In one case intra-uterine adhesions were documented by hysterosalpingography (HSG) and hysteroscopy before conception. One infant suffered from hypospadias. The diagnosis of intra-uterine bands or membranes should turn our attention to a possible intra-uterine pathology.

Endolymphatic stromal myosis (endometrial low-grade stromal sarcoma) presenting with hematuria: a diagnostic challenge.

In this case of a 41-year-old white woman who presented with hematuria, the diagnosis of metastatic endolymphatic stromal myosis (ESM) in the urinary bladder was reached on the basis of the histologic pattern and with the aid of intermediate filament typing. In the hysterectomy specimen the tumor foci of ESM were of minute size. To the best of our knowledge, this is the first report of such an unusual clinical presentation of this lesion.

Ovarian carcinoma during pregnancy: a study of 23 cases in Israel between the years 1960 and 1984.

Data from a study on malignant ovarian tumors in pregnancy in Israel are presented. During the 25-year period of the survey, 23 new cases of malignant ovarian tumors during pregnancy were diagnosed, representing an incidence of 0.12/100,000 females over the age of 14; over half of the patients were in their third decade of life at the time of diagnosis of the tumor. Ovarian malignant tumors during pregnancy are more prevalent in Jewish women of European-American origin than in those of Asian-African descent. Borderline carcinomas were found in 35% of our patients; epithelial invasive tumors were found in 30%; the other tumors were dysgerminoma (17%), granulosa cell tumor (13%), and undifferentiated carcinoma (5%). Most of the patients (74%) were diagnosed in stage I. In three cases, ovarian cancer was diagnosed during surgery for tubal pregnancy, and in two during cesarean section at term. In early-stage disease and low-potential-malignancy tumors, surgery can be conservative; thus, 14 of 23 bore a live child. In advanced disease, aggressive surgery, chemotherapy, and/or radiotherapy should be instituted. Factors affecting prognosis were age of patient, histologic type of tumor, and clinical stage of disease. Overall, the survival is much better than that for ovarian tumors in general, because most of the tumors are of low potential malignancy and are diagnosed at an early stage.
