Sex cord-stromal tumors of the ovary are the third most common types of neoplasms that develop in the ovary and account for about 5-8% of all ovarian malignancies. Juvenile granulosa cell tumor (JGCT) is one of the sex cord-stromal tumors of the ovary has distinct differences from adult granulosa cell tumor (AJCT) with regard to clinical and pathological features as well as biological behavior most frequently occuring in the first two decades of life. Usually Call-exner bodies are rare, and luteinization is frequent in JGCT. The tumor may be solid, cystic, or both. In premenarcheal girls, juvenile granulosa cell tumor usually (82%) elicits the signs of sexual precocity. The tumor should removed as soon as the diagnosis is established. Surgery is the best treatment choice for low stage juvenile granulosa cell tumor in children, but for those with high stage juvenile granulosa cell tumor or recurrent tumor, the best treatment and sensitivity of tumor to radiation therapy and chemotherapy have not yet been determined clearly. About 90% are diagnosed in early stage so, prognosis of juvenile granulosa cell tumor in children is good in most cases, but tumor with more advanced stage has worse clinical outcome correlated with its stage, presence of ruptures, grade of nuclear atypia, degree of mitotic activity. And the clinical stage at the time of diagnosis is considered most important prognostic factor. We experienced a case of ruptured juvenile granulosa cell tumor so, we present a case with brief review of literature.
Key Words: juvenile granulosa cell tumor, sexual precocity
