[A case of ovarian granulosa cell tumor with invasive adenocarcinoma of the endometrium].

A case of an ovarian granulosa cell tumor with an invasive adenocarcinoma of the endometrium, and a review of the relevant Japanese literature is reported. A 47-year-old woman was admitted to Ichinomiya Citizens' Hospital complaining of irregular uterine bleeding. On operating, an ovarian tumor was found with a broad-based polypoid mass extending into the endometrium. These lesions were histologically diagnosed as a granulosa cell tumor with an invasive adenocarcinoma of the endometrium. We have found 4 cases of a granulosa cell tumor with adenocarcinoma of the endometrium in the Japanese literature and have determined that our case with an endometrial cancer showing an invasion to the myometrium of the uterus is unique among previously reported cases.
