title: [A case of extrahepatic bile duct metastasis from gastric cancer].
abstract: A 56-year-old man was admitted with obstructive jaundice. Abdominal computed tomography and endoscopic retrograde cholangiopancreatography showed circumferential stenosis with irregular wall in lower bile duct, but the cytology of biliary brushing was no malignancy. The patient was given a diagnosis of gastric carcinoma with bone and skin metastasis. He died 2 months after the first hospital admission and autopsy was performed. The histological findings of gastric and bile duct tumor revealed signet ring cell carcinoma. The immunohistological findings of both tumors were identical. We definitively diagnosed this case as metastasis of gastric carcinoma to the bile duct.
