Figure 2: (a) Electron microscopy view at scanning magnification showing early nodular condensation of mesangial matrix associated with proliferative features (transmission electron microscopy, ×1250). (b) Expanded mesangium (M) containing abundant fibrillary deposits (transmission electron microscopy, ×20,500). (c) Capillary wall showing randomly oriented fibrillary deposits involving full thickness of glomerular basement membranes. Overlying podocyte (P) foot processes are effaced (arrow) (transmission electron microscopy × 26,500). (d) Substructure analysis of mesangial deposits showing random fibrils measuring approximately 25–29 nm in diameter and absent central lucencies on cross section, diagnostic of fibrillary glomerulonephritis (transmission electron microscopy ×43,000). P: Podocyte, E: Endothelial cell, M: Mesangium
