[An ovarian mass in childhood: a case report]

Ovarian tumors are a very heterogeneous group of neoplasms that rarely occur in pediatric age. When it happens, they are usually very malignant germ cell tumors such as embryonal carcinoma, endodermal sinus tumor or choriocarcinoma. We describe a case of a 14 years old girl who came to our observation because of an abdominal enlargement without others symptoms. The abdominal palpation revealed a big, round, painless mass from pelvic to epigastric region. A specific and accurate diagnosis was made by ultrasound. The histological examination of the surgical removed mass revealed a mucous cystadenoma that's a benign epithelial ovarian tumor.
