Mature cystic teratoma (MCT) composes 10-20% of all ovarian neoplasms. Malignant transformation of the MCT is rare and the reported incidence is 0.17–1.4 %. A 70 year old woman presented with abdominal pain of one month duration. MRI showed a well defined abdomino-pelvic cystic lesion- suggestive of right cystic ovarian neoplasm. CA125 was 4.4IU/ml. She underwent primary cytoreduction surgery. Histopathological examination confirmed it as invasive keratinizing squamous cell carcinoma arising from a mature cystic teratoma of the ovary.
Keywords: Squamous cell carcinoma, mature cystic teratoma, ovary, malignant transformation.
