Graft morphology. (A) This photograph illustrates extensive tubular atrophy. Tubular basement membranes are thickened and the interstitium is expanded by connective tissue. (B) Arteries reveal extensive accumulation of connective tissue in the media and in the expanded intima, resulting in substantial narrowing of the lumen. (C) Glomeruli also reveal obsolescence of the capillary that results in global or segmental glomerulosclerosis. The collapsed capillaries often entrap hyaline material, as depicted in this glomerulus with segmental sclerosis (PAS stain, ×400; courtesy of Dr. H.G. Rennke, Department of Pathology, Brigham and Women's Hospital and Harvard Medical School, Boston, MA, USA).
