We report about a 58-year-old man with a chronic and treatment-naive hepatitis C virus (HCV) infection of genotype 1b, who had undergone autologous stem cell transplantation twice due to multiple myeloma. Subsequently, a high-level viremic reactivation of an occult hepatitis B virus (HBV) infection and also a reverse seroconversion was observed. Furthermore, a sustained spontaneous remission of HCV infection was seen. Antiviral therapy of HBV infection was initiated with tenofovir. Seven months after therapy initiation, the patient acquired an "anti-HBc-only" status. Antiviral therapy with tenofovir is still continued. The patient is in a good clinical condition.
