[A diffuse nonsecreting osteosclerotic myeloma with polyneuropathy, organomegalies, endocrinopathies and skin changes].

A patient admitted into hospital suffering from quadriparesis, secondary to distal symmetric sensitive and motor polyneuropathy, is presented. Diffuse osteosclerotic bone changes associated to neurological symptoms were detected and histologically confirmed as non-secreting plasmacytoma, on noting the non-production of paraprotein. Also, there were endocrine, skin and systemic alterations. We comment on the association of these changes as POEMS syndrome, discussing the pathogenesis and giving details of the treatment, emphasizing the excellent response.
