A case of ovarian granulosa cell tumor with invasive adenocarcinoma of the endometrium. A case report and review of the Japanese literature.

Abstract

A 47-year-old woman was admitted complaining of irregular uterine bleeding. On surgery, an ovarian tumor was found together with a broad-based polypoid endometrial mass. These lesions were histologically diagnosed as granulosa cell tumor with invasive adenocarcinoma of the endometrium. To our knowledge, only four other cases of granulosa cell tumor with adenocarcinoma of the endometrium have been reported in Japan, although our case was unique in showing invasion to the uterine myometrium.
