Pure red cell aplasia as an autoimmune-mediated disorder.

Pure red cell aplasia (PRCA) is a clinical syndrome characterized as an anemia with almost complete absence of red-cell precursors in the bone marrow but essentially normal granulopoiesis and megakaryopoiesis ( 1). The patients generally have severe anemia with a low count of reticulocytes while the platelet count, leukocyte count and leukocyte differential are normal. The clinical course is either acute and self-limiting or chronic with rare spontaneous remissions, depending on the pathogenesis.
