Major criteria (≥ 1):

Treatment of POEMS Syndrome
Treatment of POEMS syndrome consists of radiation therapy or chemotherapy for bony lesions or bone marrow involvement sometimes followed by autologous hematopoietic stem cell transplantation Hematopoietic Stem Cell Transplantation Hematopoietic stem cell (HSC) transplantation is a rapidly evolving technique that offers a potential cure for hematologic cancers (leukemias, lymphomas, myeloma) and other hematologic disorders... read more (1 Treatment reference POEMS (polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, skin changes) is a nonautoimmune polyglandular deficiency syndrome.
