Figure 1 (a) Cellular crescents (arrow) involved 7 of 12 glomeruli (a, periodic acid–Schiff, original magnification ×40). (b) Four crescents showed fibrinoid necrosis (arrow) (trichrome stain, original magnification ×40). (c) Immunofluorescence showed mesangial staining for IgG (original magnification ×40). There was also staining for IgM, IgA, C3, and lambda light chain, but no staining for kappa light chain. (d) Electron microscopy revealed granular immune complex–type mesangial deposits without an organized substructure (arrows; original magnification ×8000).
