An eschar (/ ˈ ɛ s k ɑːr /; Greek: ἐσχάρᾱ, romanized: eskhara; Latin: eschara) is a slough [1] or piece of dead tissue that is cast off from the surface of the skin, particularly after a burn injury, but also seen in gangrene, ulcer, fungal infections, necrotizing spider bite wounds, tick bites associated with spotted fevers and exposure to cutaneous anthrax.
The incisions should be deep enough to release all restrictive effects from the eschar. The operation can be performed on the trunk, limbs, or neck, all while avoiding critical nerves, veins, and vessels. [2] Following the operation the wounds are dressed primarily with an absorbent, antimicrobial material, then wrapped lightly in a bandage.
Unstageable: Full thickness tissue loss in which actual depth of the ulcer is completely obscured by slough (yellow, tan, gray, green or brown) and/or eschar (tan, brown or black) in the wound bed. Until enough slough and/or eschar is removed to expose the base of the wound, the true depth, and therefore stage, cannot be determined.
Calciphylaxis, also known as calcific uremic arteriolopathy (CUA) or “Grey Scale”, is a rare syndrome characterized by painful skin lesions.The pathogenesis of calciphylaxis is unclear but believed to involve calcification of the small blood vessels located within the fatty tissue and deeper layers of the skin, blood clots, and eventual death of skin cells due to lack of blood flow.

A wound is any disruption of or damage to living tissue, such as skin, mucous membranes, or organs. [1] [2] Wounds can either be the sudden result of direct trauma (mechanical, thermal, chemical), or can develop slowly over time due to underlying disease processes such as diabetes mellitus, venous/arterial insufficiency, or immunologic disease.

Wounds requiring surgical closure with skin grafts or flaps (typically anything more than a small full thickness burn) should be dealt with as early as possible. [82] Circumferential burns of the limbs or chest may need urgent surgical release of the skin, known as an escharotomy . [ 83 ]
