Pathologic features of interstitial nephritis associated with inflammatory bowel disease. (A) Acute interstitial nephritis with dense interstitial inflammation composed predominantly of lymphocytes and eosinophils (hematoxylin and eosin, original magnification ×200). (B and C) Granulomatous interstitial nephritis with interstitial infiltration by mononuclear cells and noncaseating granulomas with multinucleated giant cells (arrows) (hematoxylin and eosin, Jones methenamine silver, both original magnification ×200). (D) Chronic interstitial nephritis with diffuse interstitial fibrosis and tubular atrophy. The glomerulus is preserved (Masson trichrome, original magnification ×100).
