Figure 3: Case of monoclonal immunoglobulin deposition disease in a monoclonal gammopathy of renal significance setting. 3a: Section showing enlarged glomeruli with thickened capillary walls and mesangial nodule formation with deposition of PAS positive material (PAS, ×40); 3b: The mesangial nodules and capillary walls do not show any Congophilic material (Congo Red, ×40); 3c: Tubular basement membranes are thickened (PAS, ×40); 3d: Tubular basement membranes are thickened (PASM, ×40); 3e: DIF for Kappa is negative in glomerular capillary walls and mesangial nodules (DIF for Kappa, ×40); 3f: DIF for Lambda is positive in glomerular capillary walls and mesangial nodules (DIF for Lambda, ×40).
