Figure 2.

400× microphotographs stained with HE (a,e), PAS (b), Masson’s trichrome (c), and Jones’ methenamine silver (d,f), respectively, in which different glomeruli with global mesangial widening and proliferation (M1) with cicatricial segmental sclerosing lesions (S1) are observed). Asterisks show mesangial proliferation (a–d). Arrows shows segmentary sclerosis in the tip (b,d). In the last two images we can see glomeruli with podocyte hypertrophy, forming crowns around some segments of the capillaries (arrows).
