Plasma-cell dyscrasia with polyneuropathy, organomegaly, endocrinopathy, M-protein, and skin changes: the POEMS syndrome. Distinctive radiographic abnormalities.

Abstract
Patients [3] with an unusual multisystemic syndrome characterized by polyneuropathy, organomegaly (especially hepatosplenomegaly), endocrine dysfunction, M-protein and skin abnormalities (POEMS syndrome) are discussed. Characteristic radiographic features include single or multiple osteosclerotic lesions and a peculiar variety of bony proliferation. The relationship of the disorder to multiple myeloma and plasmacytoma and the pathogenesis of the skeletal abnormalities remain obscure.
