Pure red cell aplasia (PRCA) is a rare disorder of blood production in which the bone marrow, the spongy tissue in the center of the bones, fails to function in an adequate manner resulting in anemia. The severest manifestation of this immune-mediated anemia is pure red cell aplasia. Pure red cell aplasia (PRCA) can be inherited (Diamond Blackfan Anemia, [DBA]) or acquired (aPRCA). After diagnosis, the patient received immunosuppressive treatment with a dramatic response and has been transfusion independent for more than a year.
