eschar
Pronunciation: ES-kar
Dead tissue that forms a thick, leathery scab over a full-thickness burn wound.
Full Definition
Eschar is the necrotic tissue that develops following a deep burn injury, characterized by its thick, leathery, and often black or brown appearance. This devitalized tissue forms when the burn destroys both the epidermis and dermis completely. Eschar is non-viable and must typically be surgically removed (escharotomy or excision) to prevent infection and allow for proper wound healing and grafting.
Usage
Usage note: Not to be confused with a simple scab; eschar specifically refers to thick necrotic tissue from deep burns.
