Fig. 2From: Atypical anti-glomerular basement membrane disease with membranous hyperplasia: diagnostic challenges and treatment variabilityMorphologic analysis of renal biopsy. H&E stain shows general tissue architecture and cell morphology. Periodic Acid-Schiff (PAS) stain highlights basement membranes and mesangial matrix. Jones’ Methenamine Silver (PASM) stain reveals the details of the glomerular basement membranes and mesangial regions.
