Eschar, pronounced es-CAR, is dead tissue that sheds or falls off from the skin. It’s commonly seen with pressure ulcer wounds (bedsores). Eschar is typically tan, brown, or black, and may be crusty. Wounds are classified into stages based on how deep they are and how much skin tissue is affected.
How long does it take for eschar to go away?

Why should Stable eschar not be removed?
Stable intact (dry, adherent, intact without erythema or fluctuance) eschar on the heels should NOT be removed. The reason? Blood flow in the tissue under the eschar is virtually non-existent. Therefore, the wound is susceptible to infection with limited to no ability to fight off invading bacteria.
What is the difference between necrotic tissue and eschar?
The wound bed may be covered with necrotic tissue (non-viable tissue due to reduced blood supply), slough (dead tissue, usually cream or yellow in colour), or eschar (dry, black, hard necrotic tissue). Such tissue impedes healing.
