Micrographs of renal biopsy findings. a Light micrograph of a glomerulus shows no evidence of diabetic nephropathy (periodic acid-Schiff stain). b Glomerulus shows positive immunofluorescence staining for immunoglobulin G (IgG) along a capillary wall. c Electron micrograph shows effacement of the podocyte foot process and a glomerular capillary membrane of normal thickness without evidence of capillary immune complex deposits.
