Pathological findings of the renal biopsy in the present case. Kidney specimens were stained with hematoxylin and eosin stain (a: low power field; b, d: high power field), periodic acid methenamine silver (c, e: high power field) and periodic acid-Schiff (PAS) stain (f, g: high power field). Light microscopy showed global sclerosis, tubulitis, interstitial inflammation (a), cellular crescents with segmental fibrinoid necrosis (b, c), and endarteritis of arterioles showing the accumulation of mononuclear cells in the arteriole walls (indicated by arrows) (d, e, f). Immunofluorescence microscopy showed linear deposits of IgG (f) and C3c (g) along the glomerular basement membrane (GBM)
