Perihilar FSGS
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,…

A normal glomerulus (left) and hypertrophied glomerulus (glomerulomegaly, right). Glomerulomegaly is an adaptive response to decreased nephron number (e.g. prematurity) and/or increased demand (e.g. obesity). Patients with glomerulomegaly may have…

A normal appearing glomerulus (left) compared to a glomerulus with endocapillary hypercellularity (right). Note the hypercellular capillary loop (red arrow) compared to the normal capillary lumens (black arrows). This histologic…

Membranoproliferative pattern of glomerular injury in a patient with C3 glomerulopathy. This pattern of injury typically has endocapillary proliferation, diffuse capillary wall thickening, increased mesangial matrix, and mesangial proliferation visible…
