A case of granulosa cell tumor in the broad ligament of the uterus diagnosed after laparoscopic surgery

Abstract

We report a rare case of granulosa cell tumor in the broad ligament of the uterus which was diagnosed after laparoscopic surgery. The patient was a 29-year-old married woman, gravida 2, para 0. After visiting a previous hospital with a chief complaint of irregular menstruation, she was referred to our hospital for ovarian tumor diagnosis. Transvaginal ultrasonography showed a 5-cm tumor near the normal right ovary, and MRI also showed a mass containing cystic components and some solid elements located dorsal to the normal right ovary. Levels of the tumor markers CA19-9, CA125, and SCC were within their normal ranges. Based on these results, the patient underwent laparoscopic surgery for suspected right paraovarian tumor. A tumor growing in the right broad ligament was found, and laparoscopic resection of the right paraovarian tumor was performed. The histopathological examination showed an adult-type granulosa cell tumor. The patient has had no recurrence for 15 months since surgery.
