Monoclonal Gammopathy of Renal Significance With Preexisting Connective Tissue Disease: A Case Report

Monoclonal gammopathy of renal significance (MGRS) has lately drawn the interest of physicians and pathologists due to the ability of these monoclonal proteins to cause end-organ damage. The early detection of this monoclonal protein along with hematological studies and renal biopsy are essential to establish the associated nephropathological diagnosis. We herein describe the case of a patient with MGRS and the diagnostic entity involved. She responded well to the treatment as co-managed by a multidisciplinary team of nephrologists, hematologists, and renal pathologists.
