Abstract

Malignant germ cell tumors of the ovary are uncommon neoplasms. Although 20-25% of all ovarian tumors are derived from germ cells, only about 3% of germ cell tumors are malignant. Mixed germ cell tumors contain at least two malignant germ cell elements. These lesions should be managed with combination chemotherapy, preferably BEP. Recently we experienced a case of mixed germ cell tumor with 6 components of germ cell and sarcomatous change in a 11 year old girl. Preoperative CA-125, B-hCG, aFP, LDH, a-1-antitrypsin were elevated and the final pathologic report was mixed germ cell tumor composed of endodermal sinus tumor, embryonal carcinoma, mature and immature teratoma, choriocarcinoma, dysgerminoma and sarcomatous change, Postoperative chemotherapy with 6 courses of BEP regimen was performed and all tumor markers became normal after 4 courses of chemotherapy. What we interested in this case was several components of germ cells and sarcomatous change and the sarcomatous change might be derived from the mature cystic teratoma component, so we present this case with a brief review of the literatures here.

Key Words: mixed germ cell tumor, sarcomatous change, BEP chemotherapy
