Figure 2: Light and electron microscopy findings of Patient 2 diagnosed with diabetic glomerulosclerosis (Table 1). (A) Note the slight increase in mesangial matrix and irregular thickening of the capillary walls, and also, the capsular drop on the thickened Bowman’s capsular epithelium (arrow). (B) Electron microscopy showing a diffuse and marked thickening of the glomerular basement membrane (around 1000 nm); mesangial matrix expansion; and diffuse effacement of the podocytes of foot processes. (A): PAS staining; original magnification: 300×.
