We experienced a case of ectopic pancreas in the liver which is very rare and has not been reported in Japan. A 42-year-old man was admitted to the hospital with general fatigue and jaundice. Ultrasonography and computed tomography revealed severe dilatation of the common bile duct and the left branch of the intrahepatic bile duct. Endoscopic retrograde cholangiography revealed floating stones in the common bile duct. Cholecystectomy and choledocholithotomy were performed. Intraoperative cholangiography revealed dilatation of the left branch of the intrahepatic bile duct, so left lateral segmentectomy of the liver was performed. Macroscopically no tumor was seen in the resected liver, but histologic examination revealed ectopic pancreatic tissues, which were composed of acini, ducts and no islet cells, along the dilated intrahepatic bile ducts.
