Figure 2.

Ultrastructural examination revealed small subepithelial electron dense deposits (arrow). Note the incomplete distribution of the subepithelial deposits, which involved approximately one-third of the examined glomerular capillary surface area. (a; electron microscopy, 8000×). The subepithelial electron dense deposits were not associated with GBM spike formation, consistent with stage 1 membranous alterations. Note the overlying podocyte foot process effacement (b; electron microscopy, 8000×).
