A 3-year-old boy was admitted to our hospital with an abdominal mass. Abdominal CT and MRI showed that the abdominal mass was a 6.5×6.5×6.5-cm tumor with calcification in the tumor. At operation, the tumor was located in the hepatoduodenal ligament and had adhesion to the common bile duct. The tumor was excised with the common bile duct ; a cholecystectomy was performed and the bile duct was reconstructed using a Roux-Y choledochojejunostomy. The tumor, which was surrounded by a capsule, contained upper and lower limbs, hair, fingers, and nail as a fetiform mass. There was intestine in the tumor, too. Histological diagnosis was mature teratoma. There was liver fibrosis that was thought to be induced by cholestasis with stenosis of the common bile duct. The postoperative course was uneventful and no recurrence was recognized for 6 years. To our knowledge, there are 6 previous reports of teratoma in the hepatoduodenal ligament and only 4 reports in children. The diagnosis and resection of teratoma in the hepatoduodenal ligament should be performed as soon as possible to prevent adhesion to and stenosis of the common bile duct.
