Usually these malignancies are seen in older patients and tend to be more symptomatic as compared to their benign counterparts.
Prognosis is good when there is no penetration through the cyst wall.
We present a case of ovarian benign cystic teratoma with adenocarcinomatous transformation. A forty five year old woman was suffering from pain in the abdomen since five months. Clinical examination was suggestive of right ovarian mass, which was also confirmed by ultrasonography. On exploratory laparotomy right ovarian mass was detected with adhesions to adjacent large bowel loops. The peritoneum was studded with whitish nodules varying from few millimeters to one centimeter in diameter.
