Post-infectious glomerulonephritis, abbreviated PIGN, is a rarely biopsied glomerulonephritis classically associated with a streptococcal infection.

IF
- Granular immune deposits.

- Subepithelial deposits - hump-like.[3]
- Larger when measured perpendicular to the basement membrane, if compared to membranous nephropathy.
- Typically focal.
