Post Streptococcal glomerulonephritis PSGN2. Membranous glomerulopathy3. IgA nephropathy4. Membrano proliferative glomerulo nephritis MPGNEnlarged hypercellular glomeruli Severe form - Crescent formation IF: Granular deposits of IgG, IgM, C3 along GBM EM: Subepithelial humpsDiffuse thickening of glomerular capillary wallEM: electro denseSubepithelial deposit of IgSilver- Spike like projectionFocal segmental or diffuseProliferation of mesangiumIF: IgA deposits in mesangiumEM: Electron dense mesangial deposits Thickening of GBM with proliferation of glomerular cells leukocytic infiltrationLight microscopy - Double contour or tram-track appearance - split basement membraneType 1 - Subendothelial depositsType 2 - Intramembranous deposits5. Lupus nephritis IF: Irregular mesangial capillary loop deposits Subendothelial location6. Good Pasture Dense linear IgG staining of syndrome the GBM7.
