Today’s eyeSCANdy image shows acellular scanning EM showing GBMs with variably sized discrete perforations. This is the mildest form of basement membrane damage in crescentic GN.   Photo courtesy of Dr. Stephen Bonsib

This eyeSCANdy image shows acellular scanning EM from a biopsy with membranous glomerulonephritis, stage II. The extracted deposits previously resided in the dark spaces. The lighter GBM corresponds to “spikes” on silver stai.   Photo courtesy of Dr. Stephen Bonsib.
