From: Dense deposit disease is not a membranoproliferative glomerulonephritis
Dense deposit disease crescentic pattern (a, b); dense deposit disease unclassified pattern (c, d), electron microscopy, uranyl acetate and lead citrate. (a) Ribbons of electron dense transformation of glomerular basement membranes, sometimes forming subepithelial ‘humps’, paramesangial areas and ‘waist’ areas, × 5000. (b) Electron dense transformation of glomerular basement membranes forming subepithelial ‘humps’, × 20 000 uranyl acetate and lead citrate. (c, d) Intermediate electron dense transformation in ribbons along glomerular basement membranes and mesangial regions, × 5000.
