Abstract

A 79-year-old Japanese woman diagnosed with pure red cell aplasia (PRCA) associated with thymoma and hypogammaglobulinemia (Good's syndrome) was successfully treated with cyclosporine-A after a thymectomy. We further studied the etiology of this case. A burst-forming unit erythroid (BFU-E) assay with SCF restored erythropoiesis in vitro. SCF production was reduced in bone marrow stromal cells; however, it was restored in vitro and in vivo after cyclosporine-A treatment.
