[Subacute idiopathic autoimmunehemolytic anemia with prolonged aplastic phase and erythremic reaction (author's transl)].

A case of idiopathic autoimmune hemolytic anemia with subacute onset and peculiar course is reported. In the beginning of the disease there was a long lasting severe aplastic phase, during which numerous blood transfusions were required. The low antiglobuline test titre compared with the severe hemolytic activity and the ineffective erythropoesis suggested first of all the presence of pure red cell anemia. Later on blood regeneration with erythroblastosis started and resembled the picture of erythremic myelosis. The transient course of the disease with full normalisation of all blood values and continuous remission lasting now for more than one year is a peculiar variant of idiopathic autoimmune hemolytic anemia.
