Abstract
- Obstructive jaundice associated with hepatocellular carcinoma (HCC) is an uncommon symptom caused by intraductal tumor growth, the migration of tumor necrosis, blood clots within the biliary tract, or compression of the biliary tract by the tumor. Most cases of icteric-type HCC involve a main tumor in the liver parenchyma. Bile duct HCC without a primary hepatic tumor is extremely rare, but because it shows similar clinical manifestations and imaging results to extrahepatic bile duct cancer, it is possible to misdiagnose this condition as a primary bile duct tumor or choldocholithiasis. Recently, we experienced a case of obstructive jaundice associated with an extrahepatic bile duct tumor in a 69-year-old woman. Upon radiologic studies and endoscopic cholangiography, the cause of obstructive jaundice was initially attributed to the bile duct tumor itself. However, subsequent analysis indicated that the condition was, in fact, due to bile duct thrombi associated with extrahepatic bile duct HCC.
