Abstract

Acquired amegakaryocytic thrombocytopenia (AAMT) is an unusual disease characterized by severe thrombocytopenia resulting from a marked decrease in bone marrow megakaryocytes. Various pathogenic mechanisms have been suggested, and several treatments have been tried, with varying outcomes. In some case reports, cyclosporine and anti-thymocyte globulin have had good clinical results in the treat of AAMT. There are few reports on the treatment of relapsed AAMT with cyclosporine. We report a patient with relapsed AAMT who was treated successfully with an additional course of cyclosporine. The initial remission was achieved with cyclosporine 4 years earlier and a second remission was induced by cyclosporine. Cyclosporine may be effective for relapsed AAMT that previously responded to cyclosporine.
