A crust of dry blood which forms over a wound and protects it.
A hard crust of dried blood, serum, or pus that develops during the body’s wound healing process over a sore, cut, or scratch.
The crust which forms on superficial injured areas. It is composed of fibrin, which is exuded from the raw surface, together with blood corpuscles and epithelial cells entangled in its meshes. Healing takes place naturally under this protection, and the scab dries up and falls off when healing is complete. Scabs appearing on the face without any previous abrasion are usually caused by an infection.
Crust of a cutaneous sore, wound, ulcer, or pustule formed by drying of the discharge.
A discrete superficial lesion involving localized severe roughening or pitting; more commonly, abnormal thickening of the surface layers, with or without the development of cork layers; localized hyperplasia of the surface tissues; a disease characterized by lesions of one of these types.
A scab develops on the skin or mucous membrane over a healing wound or infected region.
