Abstract
We report an extremely rare case of metastatic tumor thrombi from colon cancer in the extrahepatic bile duct. A 59-year-old man was admitted to our hospital due to obstructive jaundice. He had undergone a right hepatectomy for liver metastasis from an ascending colon cancer and partial resection of the remnant liver and right nephrectomy with partial resection of the diaphragm for local recurrence 7 years and 19 months previously, respectively. Abdominal computed tomography demonstrated a solitary lesion, approximately 2 cm in diameter, in the porta hepatis and dilatation of the intrahepatic bile duct. ERCP revealed a filling defect in the extrahepatic bile duct. Thus, extrahepatic bile duct resection and partial resection of segment IV with reconstruction of the biliary tract were performed. The resected specimen revealed a whitish tumor occupying the extrahepatic bile duct. Histologically, the tumor was determined to be a metastasis from colon cancer.
