    Abstract:
    A 47-year-old male patient was admitted because of anemia. He had been diagnosed as non-Hodgkin's lymphoma (Follicular mixed, B cell type, stage ISA) by splenectomy two years before. Bone marrow examination on admission revealed lymphoma cell infiltration and marked decrease in erythroid cells. These findings confirmed relapsed lymphoma with acquired pure red cell aplasia. After several courses of combination chemotherapy, lymphoma cells disappeared from bone marrow, but PRCA was not improved. In this case there were two times remission of PRCA. At first time, acute B type hepatitis occurred during the chemotherapy, anemia improved transiently. At the second time, mild acute hepatitis associated with herpes zoster occurred. Twenty days after hepatic injury, PRCA was improved, and continued in remission state till present day. To disclose the mechanism of PRCA in this case, erythroid colony assay of marrow cells was performed. This showed the presence of inhibitory factor in patient's serum at PRCA state, that was considered to be related to the occurrence of PRCA. These findings suggest that the improvement of PRCA was associated with the changes on immunological condition after acute hepatitis in this case.
