Membranous nephropathy


- Membranous nephropathy: H&E, IgG fluorescence, Jones silver, and electron microscopy


- thickening of glomerular basal membranes
- subepithelial immune deposits
- no increase in mesangial cell numbers
- IF: diffuse granular deposits along the GBM

  • positivity for lgG and often C3 (sometimes low level of staining for IgM or IgA).


- early subepithelial deposits
