A case of hepatocellular carcinoma in HIV-infected patient.

Persistent human immunodeficiency virus (HIV) infection induces an immuno-suppressive state and therefore malignant tumors are a very common complication. Hepatocellular carcinoma is very rare, however, because it is associated with chronic liver disease by the persistent infection of hepatitis B or C virus (HBV or HCV). We reported a case of HCC with HIV infection who had no evidence of HBV or HCV infection, and that had a rapid growth and active pulmonary metastases. Pathological findings of the resected liver showed moderately differentiated HCC and no chronic liver disease. Despite efforts to find potential HBV integration in tumor and non-tumor tissue, none was observed. To our knowledge, this is the first report of HCC in HIV-infected patient with no evidence of hepatitis virus infection.
