Immunofluorescence staining of kidney biopsy. Immunofluorescence staining shows trace mesangial staining for IgG (a), IgM (b), and kappa light chain (c) but 2+ mesangial and granular capillary loop staining for lambda light chain (d), confirming the diagnosis of PGNMID with monoclonal lambda light chain.
