Hepatocellular carcinoma and non-Hodgkin lymphoma in a patient with chronic hepatitis C and cirrhosis

Hepatitis C virus (HCV) is a hepatotropic virus, but its genome and replicative intermediates also have been detected in peripheral blood mononuclear cells in patients with chronic hepatitis C. Chronic HCV infection may lead to hepatocellular carcinoma and, in a small percentage of cases, to B-cell non-Hodgkin lymphoma. To our knowledge, coexistence of these 2 tumors has not been reported previously, We describe a case of chronic hepatitis C and cirrhosis with 2 small hepatocellular carcinomas and incidental non-Hodgkin lymphoma of a hilar lymph node found during liver transplantation. Although the mechanisms of HCV oncogenesis in hepatocellular carcinoma and in lymphoma are unclear, the presence of these 2 tumors in a single patient are in agreement with the tropism of HCV and its role in oncogenesis.
