Definition of eschar in English:



  • A dry, dark scab or falling away of dead skin, typically caused by a burn, an insect bite, or infection with anthrax.

    • ‘Early debridement of burn eschar is beneficial to wound healing.’
    • ‘Topical treatment alone is not sufficient, as it does not effectively penetrate the eschar and damaged tissue.’
    • ‘Within two weeks the lesions turned to pustules and then enlarged to painful, ulcerated nodules up to 2 cm in diameter and ulcers with black eschars.’
    • ‘The cutaneous form of anthrax presents with a darkened eschar or papule that is not painful, but can be somewhat itchy and is generally striking in appearance.’
    • ‘Formation of a local cutaneous papule ensues at the site of inoculation within three to five days after exposure; then, the papule ulcerates to form an eschar or a dark scab over the site.’


Late Middle English: from French eschare or late Latin eschara ‘scar or scab’, from Greek (see also scar).
