A Case of Simultaneous Occurrence of Granulosa Cell Tumor and Mature Cystic Teratoma in Same Ovary / 대한산부인과학회지

ABSTRACT

Mature cystic teratoma of the ovary rarely presents together with sex cord-stromal tumors. Only few cases of ovarian cystic teratoma in association with granulosa cell tumor have been reported in the literature. Granulosa cell tumors are classified as malignant tumors, but considered to be of low-grade malignancy because most granulosa cell tumors are slow growing and inactive. Long term survival rates of granulosa cell tumors are high and recurrence rate is low. Most treatment of granulosa cell tumors has been surgery but treatment after surgery is not well established. FIGO stage and mitotic index are considered to be important prognostic factors for granulosa cell tumors. We experienced a case of mature cystic teratoma and granulosa cell tumor in the same ovary of a 21-year-old woman. We present it with a brief review of literature.
