Ovarian cysts are an extremely common gynecological problem in adolescent. Ovarian Mucinous cystadenoma are rare in children. A 14-year-old presented with a history of increasing abdominal distension and pain for approximately six months. An adnexal mass measuring 24x18x13 cm was detected by abdominal ultrasonography and computed tomography. She underwent laparotomy and after surgical removal. Histopathology findings showed that the tumor was diagnosed as a mucinous cystadenoma(MCA) of the ovary. Epithelial tumors should not be forgotten in the differential diagnosis. We present a case of giant MCA of the right ovary in a 14-year-old pubertal girl and a review of the supporting literature.
