Integrated Chinese and Western medicine in the treatment of a patient with podocyte infolding glomerulopathy: A case report

Figure 1 Kidney biopsy findings. A: Light microscopic findings on periodic acid-Schiff staining. The mesangial area showed mild focal segmental proliferation and matrix thickening (arrows). The basement membrane is mildly thickened (original magnification, × 400); B: Electron microscopy of kidney biopsy specimen. Thickened glomerular basement membrane (GBM) with numerous diffusely scattered microspherical or microtubular structures (arrows), characteristic of podocyte infolding glomerulopathy (original magnification, × 12000); C: Extensive podocyte foot-process effacement with infolding into the GBM (arrows) (original magnification, × 12000); D: There are no electron-dense deposits (original magnification, × 8000).
