At low power (panel A), there are two biopsy fragments, one of which is normal colonic mucosa (bottom) while the other fragment (top) is hemorrhagic and has cleared out spaces within the fragment. At higher power (panel B), this hemorrhagic fragment has sloughed epithelial cells within the cleared out spaces. There is chronic inflammation within the lamina propria. The cleared out spaces represent ghosts of colonic glands that have undergone ischemia.
