CONGENITAL DYSERYTHROPOIETIC ANAEMIA TYPE II: A CASE STUDY

Abstract A 13-year-old girl with chronic anaemia showed features of congenital dyserythropoietic anaemia (CDA) type II. The main clinical and haematological findings were splenomegaly, a mild microcytic anaemia, and numerous bizarre and binucleate normoblasts in the bone marrow. The acidified serum lysis test (Ham’s test) performed with 5 normal sera was positive. The patient’s red blood cells showed a markedly increased expression of the i red blood cell antigen.
