Rhabdomyosarcoma of the uterus: report of two cases, including one of the spindle cell variant.

Most uterine sarcomas fall into the category of leiomyosarcoma, endometrial stromal sarcoma, or undifferentiated sarcoma. Pure rhabdomyosarcomas are extremely rare, although a rhabdomyosarcomatous element may be present as a component of an adenosarcoma or carcinosarcoma (malignant mixed müllerian tumor). This report describes two uterine rhabdomyosarcomas in 28- and 67-year-old women.

Benign, borderline, and malignant endometrioid neoplasia arising in endometriosis in association with tamoxifen therapy.

Tamoxifen therapy may result in a variety of endometrial proliferative lesions, including adenocarcinoma, and as recently suggested, proliferative changes within endometriosis. This report describes an endometrioid adenocarcinoma arising in ovarian endometriosis in a patient taking tamoxifen. There were also foci of benign and borderline endometrioid adenofibroma in the same ovary and a synchronous endometrioid endometrial adenocarcinoma in the uterus.

Bilateral ovarian cysts with squamous intraepithelial neoplasia.

We report a case of bilateral ovarian cysts lined exclusively by squamous epithelium showing multifocal intraepithelial neoplasia. The cervix showed synchronous high-grade intraepithelial neoplasia (CIN III). We interpreted the ovarian lesions as squamous carcinoma of borderline malignancy and believe that they are part of a "field change" that also involves the cervix.

Pregnancy complicated by maternal heart disease. A review of 519 women.

Between 1970 and 1983, 519 pregnancies in 405 women with heart disease were managed at the Royal Maternity Hospital, Belfast, Northern Ireland, a rate of 1.3 per 100 deliveries. In 312 (60%) the heart disease was of rheumatic origin, in 161 (31%) congenital, and the remaining 46 (9%) were a miscellaneous group that included arrhythmias, ischaemic heart disease and cardiomyopathies.
