Primary hepatocellular carcinoma with hepatitis B virus infection in a 16-year-old noncirrhotic patient.
Primary hepatocellular carcinoma metastasizing to abdominal lymph nodes and to the left lung was observed in a 16-year-old male patient. No clinically apparent chronic liver disease preceded the carcinoma and no signs of cirrhosis were detectable in the nonneoplastic liver. Hepatitis B surface antigen, hepatitis B e antigen and antibody to hepatitis B core antigen were found to be positive in the serum. By immunohistochemistry (peroxidase-antiperoxidase technique) hepatitis B surface antigen could be demonstrated in the nontumorous liver parenchyma, but not in the primary hepatocellular carcinoma itself. Serum alpha-fetoprotein was only moderately elevated (75 ng/ml), but immunohistochemically primary hepatocellular carcinoma revealed a considerable number of alpha-fetoprotein-containing cells, whereas nontumorous parenchyma did not. Carcinoembryonic antigen could be demonstrated immunohistochemically in some tumor cells of a lymph node metastasis, but not in the primary tumor or in the nontumorous liver parenchyma. We propose that primary hepatocellular carcinoma developed in this case in a symptomless hepatitis B virus carrier without preceding cirrhosis, an we exclude a simultaneous acute hepatitis B.
