[Acute benign erythroblastopenia with normochromic anemia in childhood (author's transl)]

Two boys with acute benign erythroblastopenia are described. In contrast to patients with Gasser syndrome our two boys showed a severe normochromic anemia. Furthermore, no giant proerythroblasts were detectable in their bone marrow. A blockage of differentiation from hematopoietic stem cells to proerythroblasts is possibly the cause of the disease. A special therapy, besides transfusion of packed red cells if necessary, is not required.
