Hepatitis B reactivation in a multiple myeloma patient with resolved hepatitis B infection during bortezomib therapy : case report.

It has recently been reported that hepatitis B virus (HBV) reactivation in patients with hepatitis B surface antigen (HBsAg)-negative lymphoma during or after cytotoxic therapy occurs after the use of rituximab and stem cell transplantation for hematologic malignancies.
