Abstract

Mature cystic teratoma of the ovary is the most common ovarian germ cell neoplasm representing 10-20% of all ovarian tumors. Malignant transformation rarely takes place, which is approximately 1-2% of all cases. The most common malignancy arising in mature cystic teratoma is squamous cell carcinoma. The prognosis of malignant transformation developing in mature cystic teratoma is poor and the management is not established due to the rarity of malignant degeneration. A case of stage Ia squamous cell carcinoma which developed in mature cystic teratoma of left ovary in a 43-year-old female is presented. The ovarian tumor was woman's fist-sized with intact capsule. Left oophorocystectomy was done. Above case with a brief review of literature is given.
