Abstract

Malignant transformation of mature cystic teratoma is a rare complication. Most com-mon malignant transformation of mature cystic teratoma is squamous cell carcinoma, which represents about 75 to 80% followed by adenocarcinoma in 6 to 7%. It is generally consi-dered that prognosis is extremely poor in case of adenocarcinoma associated with cystic te-ratoma. In this paper, we describe an adenocarcinoma arising from a mature cystic teratoma of left ovary in 47 year old woman. Left ovary was measured 18x15x7cm, 1,295gm in size. Uterus and right ovary were normal appearance. Left ovarian cyst was adhered to omentum and peritoneum. But neither rupture of cyst nor ascites were found at laparotomy. A brief review of concerned literatures was presented.
