Fig. 3From: Atypical anti-glomerular basement membrane disease with membranous hyperplasia: diagnostic challenges and treatment variabilityTEM analysis of renal biopsy. (A) The left panel shows extensive podocyte effacement and irregular thickening of the glomerular basement membrane (GBM). (B) The middle panel reveals subepithelial deposits characteristic of membranous nephropathy, with spikes and dome appearance of the GBM. (C) The right panel highlights areas of GBM disruption and cellular interposition, suggesting active glomerular injury. Scale bars represent 2 μmBack to article page
