Sex cord stromal tumors (GCT) of the ovary compose just 5% of ovarian tumors. Most of them are granulosa cell tumors (GCT). There are two types of tumors, juvenile (JGCT) and adult type (AGCT), which have different clinical and histopathological features. JGCT represents only 5% of GCT. GCT is characterized by secretion of estrogen. Patients may present with vaginal bleeding in adult type, and sexual pseudoprecocity in juvenile type, as results of prolonged exposure to tumor-derived estrogen. Surgery is a principle of treatment and required for definite tissue diagnosis, staging, and tumor debulking. Survival of patients with GCT is generally excellent because most patients present with early stage disease. Because of the propensity of GCT to recur years after initial diagnosis, prolonged surveillance such as physical examination and serum tumor markers such as estradiol and inhibin is reasonable. We present 5 cases GCT, 4 AGCT and 1 JGCT, with brief review of literature.
