A case of congenital dyserythropoietic anemia in a male Chinese.
A 38 yr-old man has chronic non-spherocytic hemolytic anemia which was attributed to glucose-6-phosphate dehydrogenase (G-6PD) deficiency for the past 20 yr. A diagnosis of congenital dyserythropoietic anemia Type II (CDA) was made because of the bone marrow findings and electron microscopic appearance of the peripheral erythrocytes. Congenital dyserythropoietic anemia, though well recognized in Caucasians, has not hitherto been described in Chinese. Erythrocyte G-6PD deficiency has been found to have an incidence of 5.5% in Southern Chinese. The coexistence of CDA Type II and G-6PD deficiency in this patient may be a chance finding or there may be an interaction between the 2 abnormalities in the clinical manifestations of CDA Type II and G-6PD deficiency.
