ABSTRACT
A POEMS syndrome(polyneuropathy, organomegaly, endocrinopathy, monoclonal M protein, and skin lesion) is a rare multisystem disease of unknown cause with varying clinical manifestations. POEMS- associated renal disease is also a rare condition. We experienced a 42-year-old male who had been suffered from generalized edema, low extremity weakness and pain. He also had a significant hematuria, proteinuria, azotemia, hepatospenomegaly, intraperitoneal lymph node enlargement, hypothyroidism, IgA lamda type monoclonal gammopathy, specific skin change and ascites. In renal biopsy, membranoproliferative features with enlarged glomeruli, mesangial proliferation, capillary wall thickening and paucity of immune deposit was noted. We suppose that renal insufficiency could come from POEMS syndrome. His symptoms such as low extremity pain, azotemia and generalized edema were improved by hemodialysis and use of prednisolone. At present, he is under the treatment of prednisolone and melphalan.
