Malignant transformation in mature cystic teratoma of the ovary: a retrospective study of eight cases and review of literature

Abstract

The rate of malignant transformation in MCT increases with age and is much higher in the postmenopausal age group. Moreover, although SCC is still the commonest, transitional cell carcinoma (TCC) may also develop not infrequently as malignancy apart from other rare differentiations such as adenocarcinoma or malignant melanoma in an MCT.
