POEMS syndrome. Study of a patient with proteinuria, microangiopathic glomerulopathy, and renal enlargement

Abstract

We studied a patient with POEMS syndrome (plasma cell dyscrasia with polyneuropathy, organomegaly, endocrinopathy, monoclonal [M]-protein, skin changes) who was also found to have renal enlargement and microangiopathic glomerulopathy. The latter finding is unusual in POEMS syndrome patients, and the associated symptoms can lead to confusion in diagnosis. We emphasize the importance of considering POEMS syndrome in the differential diagnosis of patients who have unexplained neuropathy, scleroderma-like skin changes, and/or monoclonal gammopathy.
