Abstract

Mature cystic teratoma of the ovary is the most common ovarian germ cell tumor and benign, but malignant transformation occurs in less than 2% of benign mature teratoma. Of the malignancies arising in teratomas, squamous cell carcinoma is the most common, however, carcinoid tumors or adenocarcinomas arising in mature cystic teratoma are uncommon, especially simultaneously. We present an unusual case of premenopausal woman having carcinoid tumor and mucinous adenocarcinoma simultaneously arising in ovarian muture cystic teratoma.
