Intraabdominal recurrence of granulosa cell tumor of the ovary twenty years after initial surgery—a case report—

Abstract

A 72-year-old woman was admitted due to lower abdominal discomfort. She had had a simple hysterectomy with bilateral salpingo-oophorectomy for rupture of the right ovary 20 years ago, and the surgical removal of an intraabdominal synovial sarcoma tumor 10 years ago. Imaging studies revealed an intraabdominal tumor ; a synovial sarcoma relapse was diagnosed. However, the detailed examination of both the present specimen and the tissue resected 10 years ago suggested that the current lesion was histologically similar to the granulosa cell tumor, which had been noted in the ruptured ovary 20 years ago. Thus, an intraabdominal granulosa cell tumor of the ovary recurred 20 years after initial surgery. Our case highlights that recurrent disease should be included in the differential diagnosis when evaluating an intraabdominal tumor in a patient with a history of a gynecological tumor such as a granulosa cell tumor.
