Acquired Pure Red Cell Aplasia is a rare bone marrow disorder characterized by an isolated decline of red blood cells (erythrocytes) produced by the bone marrow. It is characterized by an absence of red cell precursors (reticulocytes) in the marrow and a low red blood cell count. Lymphocytes accounted for 20-30% of marrow cells, and numbers of T8 suppressor/cytotoxic cells in peripheral blood were greatly increased. For patients who present both pure red cell aplasia … Diamond-Blackfan anemia is a congenital form of PRCA.
