RESUMO
Introduction: Ovarian Granulosa Cell Tumors (GCT) is a potentially malignant tumor. Accurate diagnosis requires histological and immunohistochemical study. The treatment of choice is surgical staging and debulking staging according to International Federation of Gynecology and Obstetrics (FIGO) criteria, preferred by laparoscopy. The therapeutic role of adjuvant therapy is unclear. Relapses arefrequent, usually late and insidious. Case Report: we report two cases of Ovarian Granulosa Cell Tumor. First case, a laparoscopic oophorectomy for complex adnexal cyst, intraoperative study does not differentiate between Granulosa Cell Tumor or clear cell carcinoma of the ovary, so we performed a complete staging surgery by laparoscopy. Second case aparaortic recurrence twenty years after first surgery. Non-steroidal anti-androgen therapy was useful to control progression of the disease, finally laparoscopic excision of the lesion. Conclusion: A complete surgery in the management of Granulosa Cell Tumor is recommended. Relapses can occur very late and response to chemotherapy is poor, so it is important to perform a careful initial staging or debulkingprocedure because intraoperative pathological diagnosis is difficult and confusing.
