[Acute erythroblastopenia due to Parvovirus B19 revealing hereditary spherocytosis].

Acute Parvovirus B19 infection is responsible for blocking the erythroblastic line, usually with no consequences on hematopoiesis except in patients with chronic hemolytic anemia in whom it can evolve to potentially serious acute anemia. We report 2 observations of acute erythroblastopenia revealing hereditary spherocytosis in 2 children (1 boy and 1 girl) of non-consanguineous parents.
