Sideroblastic Anemias
Key Points
Sideroblastic anemia can be acquired or congenital. Ringed sideroblasts on a bone marrow biopsy are pathognomic. Anemia is usually microcytic in congenital sideroblastic anemia and macrocytic in acquired sideroblastic anemia. Serum iron, ferritin, and transferrin are typically increased. Treat the underlying disorder and considerpyridoxinein congenital cases or recombinant erythropoietin in acquired cases.
