Transient erythroblastopenia due to human parvovirus B19 infection: a case report of a boy suffering from purpura.

Transient erythroblastopenia of childhood (TEC) was observed in a boy infected by human parvovirus B19 (B19) before the manifestation of the typical clinical picture of erythema infectiosum (EI). He did not have any apparent symptoms of anemia, and spontaneous resolution of erythroblastopenia was observed before the manifestation of the symptoms of EI. The difference between primary B19 infection and classical TEC is discussed.
