Light microscopic images of renal biopsy. a The biopsy highlighted 14 glomeruli, of which two were obsolescent, four were adherence lesions with fibrous crescents showing previous active IgA vasculitis (periodic acid-silver methenamine stain; original magnification, ×200). b, c Other glomeruli showed little hypertrophy and minor glomerular abnormalities (b periodic acid-silver methenamine stain; c Periodic acid-Schiff stain; original magnification, ×600). d Tubulointerstitial atrophy developed and showed an arteriosclerotic lesion with hypertension and diabetes (Masson trichrome stain; original magnification, ×40)
