Perihilar variant of focal segmental glomerulosclerosis (FSGS). Hyaline deposition and sclerosis occur at the vascular pole of the glomerulus. This variant is believed to be a secondary form of FSGS, occurring as an adaptive response to other injuries resulting in loss of functioning nephrons, such as in obesity-related kidney disease.
