Résumé
Malignant transformation is a rare complication in a mature cystic teratoma of the ovary, usually being reported less than 2% of cases. The most common malignant tumor arising from a mature cystic teratoma of the ovary is a squamous cell carcinoma. However, adenocarcinoma is reported extremely rare, in most cases it was impossible to tell the source of the malignancy. We experienced a case of papillary carcinoma of thyroid glands arising from mature cystic teratoma of the ovary and report this case with a brief review of literature.

The mature cystic teratoma is the most common ovarian neoplasm arising in young women and comprises approximately 10-20% of all ovarian tumors. But malignant transformation is an uncommon complication in a mature cystic teratoma(dermoid cyst) of ovary, usually being reported in about 2% of cases. Among those rare tumors with malignant change in a mature cystic teratoma, 80% are squamous cell carcinoma, 7-8% are sarcomas of various types, 6-7% are adenocarcinoma, and the remainder include thyroid carcinomas, carcinoids, and melanomas, and choriocarcinomas, and mixed malignancies. We experienced a case of adenocarcinoma arising in mature cystic teratoma of the ovary and report this case with a brief review of literatures.
