A 63-year-old man was admitted to hospital in 2003 for treatment of a hepatocellular carcinoma (HCC). He was negative for HBs antigen (HBsAg) and anti-HCV antibody, and positive for anti-HBs. He had a past history of chronic hepatitis B. In 1986, HBsAg had become negative with the development of anti-HBs. In 2003, an HCC was detected and liver resection was carried out. Histological examination revealed moderately differentiated HCC and slightly fibrotic liver. It is suggested that a diagnosis of HCC, combined with negativity for HBsAg and anti-HCV antibody, may include cases of past recovery from chronic hepatitis B, such as this case.
