Pure Yolk Sac (Endodermal Sinus) Tumor of the Liver: A Case Report

Hepatic tumors are rare in children. About 50%- 60% of these tumors are malignant. 65% of the liver malignancies are hepatoblastomas and most of the remainder are hepatocellular carcinomas. Yolk sac tumor (YST) is an extremely rare tumor of the liver. We report on a hepatic yolk sac tumor in a 15-month-old girl who presented with acute abdomen. She was diagnosed initially as intussusception, while ultrasonography and CT-scan indicated a liver mass. Finally, yolk sac tumor was diagnosed surgically and histopathologically.
