Abstract
Immature ovarian teratoma is a rarely seen germ cell tumor. Although testicular germ cell tumors and their association with chemotherapeutic retroconversion have been reported at a substantial rate of 2%-8% in the literature, the retroconversion of immature ovarian teratoma to mature teratoma is quite uncommon. It is important to reveal this conversion by biopsy for establishing a subsequent treatment chart of patients. A 45-year-old female patient was operated on due to immature ovarian teratoma. Then, she was re-operated on, because local recurrence occurred during the drug-free follow-up period, and systemic chemotherapy was administered. Liver metastasis was detected after chemotherapy, and the liver biopsy demonstrated a mature teratoma. This case is presented in this paper.
