چکیده
up almost 20% of all ovarian neoplasms. Although they are almost always benign tumors, the rare development of cancer deserves emphasis. The most common malignant change in a dermoid cyst is squamous cell carcinoma, followed by adenocarcinoma and carcinoid tumor (1-3). Primary of ovarian carcinoid tumors are uncommon and the majority of them are associated with mature cystic teratomas (4). Robboy et al (5) divided these tumors into three types: the insular type, trabecular type, and strumal carcinoid type. We report herein a case of insular carcinoid tumor arising from a mature cystic teratoma, which was examined by histological and immunohistochemical methods.
