(medicine) A superficial structure of dead tissue, usually hardened, commonly, but not necessarily dark, adhering to underlying living or necrotic tissue, caused by gangrene or a burn

...stable intact eschar on the heels should not be removed. Blood flow in the tissue under the eschar is poor and the wound is susceptible to infection. The eschar acts as a natural barrier to infection by keeping the bacteria from entering the wound. If the eschar becomes unstable (wet, draining, loose, boggy, edematous, red) it should be debrided according to the clinic or facility protocol
