A A glomerulus with mild mesangial expansion, proliferation, and sclerosis. Rare foam cells are seen beneath the bowman capsule. Interstitial fibrosis is also evident adjacent to the glomerulus (Trichrome stain); B A glomerulus with mild mesangial proliferation, slight mononuclear leukocytic infiltration within interstitium is evident (H&E stain); C same glomerulus as B, with higher power showing mild mesangial proliferation (H&E stain); D Tiny focus of adhesion and rare foam cells deposition (arrows) at tip location (Trichrome stain)
