Objective:
The aim of this study was to report a case of extraovarian granulosa cell tumor and to describe its relevance to the histologic origin of granulosa cell tumors and to clinical practice.
Methods:
The clinical course and histopathology of the case were reviewed, and a literature search for other reported cases was performed.
Results:
A 67-year-old woman presented with postmenopausal bleeding and a pelvic mass. Laparotomy revealed a 16-cm mass arising from the right pelvic sidewall, filling the pelvis, and involving the bladder and rectosigmoid colon. Both ovaries appeared normal and were separate from the mass. Pathologic examination revealed granulosa cell tumor. A literature search revealed no recently reported cases of extraovarian granulosa cell tumor.
Conclusions:
Granulosa cell tumors can arise in locations other than the ovary and may be derived from the mesenchyme of the genital ridge. Women who have undergone oophorectomy may have the potential to develop granulosa cell tumors.
