Abstract

Hepatocellular carcinoma (HCC) is the most common primary liver tumor. However extrahepatic growing hepatocellular carcinoma has rarely been reported and is characteristically large and encapsulated. Extrahepatic growing HCC which invaded right adrenal gland is very difficult to differential diagnose between hepatocelluar carcinoma and adrenal gland tumor. We report a 56-year-old male patient with almost one-year-history of right flank pain. Dynamic computerized tomography (CT) showed the tumor grew so large that invaded directly right adrenal gland. For this reason, we had to rule out hepatocelluar carcinoma, adrenal cortical carcinoma, and pheochromocytoma. In diagnosis process, we got much help from immunohistochemistry. Therefore, we presented a case of pedunculated hepatocellular carcinoma mimicking adrenal cortical carcinoma, diagnosed by immunohistochemical stains.
