A Case of Advanced Squamous Cell Carcinoma Arising in Mature Cystic Teratoma of the Ovary / 대한산부인과학회잡지

ABSTRACT

Mature cystic teratoma comprises approximately 10-20% of all ovarian neoplasms and malignant transformation from mature cystic teratoma is reported to be less than 2%. Squamous cell carcinoma is the most frequent malignancy (80%) arising in mature cystic teratoma followed by sarcoma (7-8%), adenocarcinoma (6-7%), carcinoid tumor, melanoma, choriocarcinoma (1-2%). Prognosis of squamous cell carcinoma in mature cystic teratoma is reported much poorer than that of epithelial ovarian cancer with the same stage. We experienced one case of squamous cell carcinoma arising in mature cystic teratoma.
