Pure red cell aplasia associated with parvovirus B19 infection occurring late after allogeneic bone marrow transplantation.

Differential diagnosis for anemia late after allogeneic stem cell transplantation is broad. In this report, we describe a case of severe anemia secondary to pure red cell aplasia associated with human parvovirus B19 infection over 8 years after allogeneic bone marrow transplantation. Characteristics of parvovirus B19 infection and the immunosuppressed state after allogeneic stem cell transplantation are reviewed. Copyright 2004 Wiley-Liss, Inc.
