Multiple Myeloma as a rare cause of membranoproliferative glomerular nephritis

Multiple myeloma (MM) is a relatively uncommon cancer characterized by the neoplastic proliferation of plasma cells producing a monoclonal immunoglobulin(Ig). Renal failure in multiple myeloma is around 48% and it may be the presenting manifestation of MM.[1] Renal involvement is multifactorial including light chain cast nephropathy amyloidosis, monoclonal Ig deposition disease and less frequently cryoglobulinaemic glomerulonephritis and proliferative glomerulonephritis.[2-5] Hence membrano proliferative glomerulonephritis (MPGN) is a rare form in MM. Here we report a case of multiple myeloma with MPGN in a 60-year-old male who succumbed to death while on chemotherapy.
