Background The ultrastructural findings of membranous nephropathy (MN) are well described. Recently, podocyte infolding in the glomerular basement membrane (GBM) has been observed to be a unique ultrastructural finding formed from diffuse spherical microparticles and microtubules in the GBM. However, these alterations of glomerular epithelial cells have not been well characterized in MN.
