Abstract

Mature cystic teratoma of the ovary is the most common ovarian germ cell neoplasm comprising (10-20%) of all ovarian tumors and almost always benign, but it can be developed into malignancy rarely. We have recently experienced one case of squamous cell carcinoma arising in mature cystic teratoma of the right ovary in 67-year-old postmenopausal woman. The ovarian tumor was measured 17x12.5x8 cm in size and had not intact capsule, and the peritoneal washing cytology was positive. The survival rate with cancerous dermoid is very poor. Neither of two forms of postoperative treatment (radiotherapy and chemotherapy) has any significant influence on survival. We report above case with a brief review of literature.

Key Words: Ovary, Mature cystic teratoma, Squamous cell carcinoma
