case_images: Staining for C4 and C1q was both negative with the latter seen on Figure 5.
case_images: There is mesangial hypercellularity and mild thickening of glomerular basement membrane along with electron dense deposits (ED) in mesangial, subendothelial, and subepithelial locations (electron microscopy, x 8000).
