Dermoid cysts account for approximately 25% of all ovarian tumors. Presence of pure squamous cell carcinoma is very rare findings (1-2%), which is attributable to malignant transformations into a pre-existing dermoid cyst. As there are no specific signs and symptoms to suggest malignancy in dermoid cyst, therefore it is difficult to predict, and most cases are diagnosed post-operatively. We hereby report a case of dermoid cyst ovary with malignant transformation into squamous cell carcinoma in 50 years post-menopausal women. Who presented with complaint of abdominal pain and increased frequency of micturation. Hysterectomy with Bilateral-salpingo-oophorectomy (BSO) with omentectomy was done. Right ovary showed huge cyst with hair shaft, sebaceous materials and a small solid area. Histopathological examination revealed squamous cell carcinoma was arising within the dermoid cyst.
