  • Thickened and hyalinized vessel walls, hyaline deposition in arterioles, fibroelastic hyperplasia in lobular / arcuate arteries
  • Tubular atrophy, interstitial fibrosis, periglomerular fibrosis and glomerulosclerosis
  • Hyaline arteriolosclerosis: outer wall thickened by PAS+ eosinophilic and homogenous material, with atrophy of smooth muscle cells in vessel wall and uniform basement membrane thickening; more common in afferent arteriole and vessels lacking an internal elastic lamina; associated with diabetes, hypertension and increasing age; IgM and C3 deposition
