Abstract

Pure red cell aplasia (PRCA) is a rare hematological disorder characterized by severe normochromic normocytic anemia and reticulocytopenia due to erythroid progenitor depletion in an otherwise normal bone marrow. Autoimmune hemolytic anemia (AIHA) is caused by autoantibodies directed against red blood cells with normocytic or macrocytic anemia with reticulocytosis. Both diseases can develop in conjunction with various underlying diseases, such as immunological disorders. Although rare, there have been a few cases of AIHA followed by PRCA. Here, we report a patient who developed PRCA following AIHA and was later diagnosed with systemic lupus erythematosus.
