Abstract :
Mature cystic teratomas of ovary are common benign germ cell tumors that constitute about 20% of all the ovarian tumors. These tumors however have a rare potential for malignant transformation 0.17-2% and therefore there is a requirement for intraoperative diagnosis to establish an appropriate line of treatment. Incidence of mature cystic teratoma undergoing multiple types of malignant transformation in the same patient is extremely rare and only a small number of such cases have been published in literature. Histopathology and immunohistochemistry are the gold standard for diagnosis and remains the mainstay for defining the treatment course and prognosis.
