Abstract
|
|
|
Hepatocellular carcinoma has a great tendency to invade blood vessels,
particularly the portal vein. Invasion into the biliary lumen has been
considered to be a rather rare event. Ultrasonogram and endoscopic
retrograde cholangiopancreatography of the patient, a 65-year-old man
presenting with obstructive jaundice, revealed an obstructing mass at the
common hepatic duct and dilatation of the intrahepatic bile ducts. Abdominal
computed tomography and hepatic angiogram showed no abnormal mass and
abnormal staining in the liver. Obstructive jaundice due to Klatskin’s tumor
was suspected preoperatively. During operation, although no tumor was
palpable in the liver, an intraductal tumor measuring 3.5×3.0 ㎝ was found
in the common hepatic duct. Bile duct resection was performed in a patient.
Histologically, the tumor, a hepatocellular carcinoma showing abundant
eosinophilic cytoplasm, was structurally arranged in a solid and trabecular
pattern. We report a case of hepatocellular carcinoma mainly presenting as
Klatskin tumor.
