Abstract

Malignant transformation within a mature cystic teratoma occurs in less than 2% of cases and most commonly results in a squamous cell carcinoma. Other reported malignancies include adenocarcinoma, various pure sarcomas, melanomas and basal cell carcinomas, and anaplastic carcinoma. We report a rare case of a 46-year-old woman with undifferentiated sarcoma arising in a teratoma of the ovary.
