Ovarian tumor with mature teratoma with squamous differentiation in a postmenopausal female

Mature cystic ovarian teratomas are the commonest germ cell tumour accounting for about 30-45% of all ovarian neoplasms and around 60% of all benign tumors arising in the ovary. The reported incidence of malignant transformation in MCT is approximately 2%. A rare case of squamous cell carcinoma arising in a dermoid cyst of the ovary presenting in a postmenopausal female is presented here. A 60-year-old postmenopausal lady, presented with the complaint of pain in lower abdomen for 2 years and a large complex abdomino-pelvic mass on examination and investigations. Final histopathology was reported as squamous cell carcinoma arising from mature cystic teratoma of right ovary. Primary cytoreductive surgery was done and a surgical stage IIB was assigned. In view of the poor prognosis, adjuvant chemotherapy was started.
