Abstract
Hematologic findings and clinical courses of five cases with sideroblastic anemia, consisting of two cases with hereditary type and three with acquired type, were presented. Special studies included observations on the bimorphism of erythrocytes and abnormalities in sideroblasts. Chromosomal analysis of marrow cells revealed karyotypic abnormalities in two of four cases tested. The chromosomal findings were discussed in relation to the nature of sideroblastic anemia. Also presented was the summary of hematologic findings of cases with sideroblastic anemia reported in this country.
