Kidney involvement in Crow-Fukase syndrome.

Crow-Fukase syndrome, also known as POEMS syndrome, is a rare plasma dyscrasia characterized by monoclonal gammopathy and various combinations of polyneuropathy, organomegaly, endocrinopathy and dermatological changes, and their initials stand for the acronym POEMS. Substantial kidney involvement is rarely related to this disease. Our report is about five patients suffering from the POEMS syndrome with kidney involvement that rapidly progressed to end-stage renal disease.
