The findings were felt to be consistent with stage II-III membranous glomerulopathy (Figures 1-3).
Jones methenamine silver stain of glomerulus. Note the holes in the glomerular basement membranes, which are cut en face (solid arrow). Compare with normal appearance of glomerular basement membrane (dashed arrow) (original magnification X400).

A, Immunofluorescence staining with FITC anti-Igk. Detail of a glomerulus with granular deposits along the capillary loops (original magnification, X400). B, Electron microscopy of an affected glomerulus revealed occasional subepithelial electron dense deposits (arrows) (original magnification X12 600).
