Abstract
Jaundice usually occurs in the late stages of hepatocellular carcinoma (HCC). Obstructive jaundice is rarely seen as an initial presentation of HCC, as opposed to cholangiocarcinoma. Various causes of obstructive jaundice in these cases also known as “Icteric HCC” have been described such as tumour thrombi, compression, infiltration or tumours arising from native hepatocytes in the bile duct. We present a case of 74-year-old gentleman with “Icteric HCC” that clinically and radiologically mimicked cholangiocarcinoma for which the patient underwent left hepatectomy with Roux-en-Y hepaticojejunostomy. Histopathology revealed dilated large duct with polygonal sheets of cells of hepatoid morphology which stained diffusely positive for both glypican 3 and Hep-par 1. The epicentre was in the left hepatic duct with no discernible liver lesion and the tumour probably originated from the ectopic hepatocytes within the biliary duct The patient was disease free at 1.5 years of follow up. In conclusion, HCC should be a differential for obstructive jaundice. Patients with such “Icteric HCC” benefit from surgical resection with favourable outcomes. The prognosis in such patients is better than in patients of HCC with jaundice due to hepatic insufficiency.
