Renal disorder preceding multiple myeloma.

Renal disorders preceding multiple myeloma (MM) is a rare type of presentation for plasma cell dyscrasias. We report a case of 40-year-old female who first admitted to the hospital with symptoms and signs of weight loss, nausea and vomiting, and with findings of proteinuria renal dysfunction and anemia. Renal biopsy revealed light chain deposition and findings mimicking membranoproliferative glomerulonephritis (MPGN). Investigation of the patient for plasma cell dyscrasia was resulted in normal findings. After 28 months, she was re-evaluated and MM was diagnosed.
