Extraovarian Granulosa Cell Tumor of Mesentery : A Case Report

الملخص EN

Extraovarian granulosa cell tumor (GCT) is a very uncommon tumor, assumed to arise from the ectopic gonadal tissue along the embryonal route of the genital ridge.

A 54 years old female patient presented with a mass and acute pain in abdomen.

Exploratory laparatomy revealed hemoperitoneum with a large mesenteric mass measuring 13 × 12 cm in size, showing extensive areas of haemorrhages.

Histopathological examination of the excised mass showed features of adult-type GCT.

As the patient had a history of hysterectomy with bilateral salpingo-oophorectomy 10 years ago for ‘‘leiomyoma’’ with no evidence of GCT of the ovary in the histopathology report, a diagnosis of extraovarian GCT was made.

A diagnosis of extraovarian GCT should be carried out after excluding any previous history of GCT of the ovary.

Tumor rupture with haemoperitoneum is a well-known complication of GCT.

Extraovarian GCT is a rare tumor with only 10 cases reported in literature.

The case is presented for its rarity.
