title: Heterotopic gastric mucosa in intrahepatic bile duct, presenting with hemobilia: a case report.
abstract: We present a 66-year-old man with unique heterotopic gastric mucosa in the intrahepatic bile duct causing hemobilia. Endoscopic retrograde cholangiography showed irregular stenosis of the left intrahepatic bile duct, and a provisional diagnosis of cholangiocarcinoma was made. Therefore, partial hepatic lobectomy and cholecystectomy were performed. Histological examination of the liver showed the presence of ectopic gastric mucosa in the intrahepatic bile duct containing mucous glands with parietal and chief cells and bile. Heterotopic gastric mucosa in the intrahepatic bile duct is a rare cause of hemobilia.
