• A lengthy aplastic crisis, manifest by pancytopenia and fever, was observed in a young woman with sickle cell β°-thalassemia. Bone marrow aspirates and biopsy specimens showed marrow necrosis, and reticuloendothelial scans showed widespread abnormalities consistent with marrow infarction. Physical damage to erythropoietic tissue as well as arrest of erythropoiesis can cause acute erythroblastopenia in patients with sickle cell anemia. (Arch Intern Med1982;142:2223-2225)
