Glomerular sclerosis Segmental glomerulosclerosis 2021-01-10T13:21:47Z Glomerular changes can be focal (only in some glomeruli) or diffuse (in all or almost all the glomeruli), and segmental (only a part of the glomerulus) or global (the entire glomerulus). Segmental solidification of the glomerular tuft by increased extracellular matrix, causing glomerular capillary obliteration and can include hyalinosis, foam cells, hypertrophy of overlying glomerular epithelial cells, podocyte depletion, halo and adhesion of the tuft to the Bowman capsule.
