[Isolated metastasis of the granulosa cell tumor of the ovary in the small intestine mesentery 19 years after salpingo-oophorectomy]

Abstract

Introduction: Granulosa cell tumour is uncommon malignant tumor which belongs to the sexual cord-stromal tumors of the ovary. It arises from the specialized stromal cells of the ovary. These tumors are unilateral in 95%. Over 90% of patients survive more than 10 years after surgery, but the recurrence may appear even 25 years after surgery.

Case report: The authors present a 54-year-old woman who was admitted for abdominal pain and ultrasonography revealed tumor in the abdomen. During the surgery, a spheric, well circumscribed tumor of the mesentery, close to the forth portion of duodenum, was excised. Histological and immunohistochemical examinations verified that it was the metastasis of the granulosa cell tumor of the ovary that had been removed 19 years ago when salpingo-oophorectomy had been performed. Postoperative recovery was uneventful. Twenty six months later, the tumor 4 cm in diameter recurred, and was localized to the left of duodenum, close to the inferior mesenteric artery, which was perfectly ideally, together with fat tissue and surrounding lymph nodes. She has remained symptom free so far.

Conclusion: To the best of our knowledge, this is the first case of the isolated metastasis of the granulosa cell tumor in the mesentery, that appeared 19 years after original surgery.
