title: [A case of the extrahepatic bile duct carcinoid tumor].
abstract: A 76-year-old man presented with back discomfort and jaundice. CT and MRI of the abdomen revealed a mass in the common bile duct. Cytology of the bile juice obtained by percutaneous transhepatic cholangio-drainage revealed class V. The patient underwent laparotomy and pancreatoduodenectomy. Pathology showed a carcinoid tumor of the biliary tract, 14 x 10 mm in size. Grimelius staining demonstrated the presence of argyrophilic granules. On immunochemistry, the tumor stained positive for chromogranin A and synaptophysin. He had two liver metastases 8 months postoperatively.
