Abstract |
Congenital dyserythropoietic anemia(CDA) is characterized by ineffective erythropoiesis an d increased numbers of multinucleated red cell precursors in the marrow. This syndrome has b een subdassified on the basis of morphologic and serologic differences in the red cell pecursors. There are some patients with congenital dyserythropoietic anemia who do not fit into the conventional classification of type I, II, or III congenital dyserythropoietic anemia. Patients differ from type II congenital dyserythropoietic anemia in that they have a negative reaction in the Ham's test. some investigators consider this a type IV congenital dyserythropoietic anemia.
We experienced a case of congenital dyserythropoietic anemia IV in a 3 month-old boy. Diagnosis was established by serologic findings, peripheral smear, bone marrow finding, and electon microscopic findins. |
