Abstract

Mature cystic teratoma of the ovary is the most commom ovarian germ cell tumor and almost benign. Malignant transformation occurs in less than 2% of benign mature teratoma. Squamous cell carcinoma derived from ectoderm is the most frequent malignancy. Prognosis of squamous cell carcinoma in ovarian mature teratoma is generally poor but there is no consensus on optimal thrapy. We report one case of squamous cell carcinoma arising from mature cystic teratoma with a brief review of the literature.

Key Words: Ovarian mature teratoma, Squamous cell carcinoma
