What Stains are Used to Identify Kimmelstiel-Wilson Nodules?
Several histological stains are utilized to identify Kimmelstiel-Wilson nodules: - Periodic acid-Schiff (PAS) stain: Highlights the glycoprotein content in the nodules. - Silver stain: Demonstrates the thickened glomerular basement membrane and mesangial matrix expansion. - Hematoxylin and eosin (H&E) stain: Provides general histological context, showing eosinophilic nodules.
