Sarcoidosis of the uterus.

The present case of sarcoidosis of the uterus and the previously reported cases are reviewed. Uterine sarcoidosis is usually detected during the investigation of abnormal uterine bleeding in patients with prior evidence of sarcoidosis in another site. However, in several of the reviewed cases, either the uterus was the site of the initial diagnosis of sarcoidosis or its involvement was detected soon afterward. When hysterectomies were performed on patients with endometrial involvement, the myometrium was usually found to contain nonnecrotizing epithelioid granulomas. By contrast, uterine tuberculosis usually spares the myometrium. The differential diagnosis between uterine sarcoidosis and uterine tuberculosis is discussed.
