A localized shedding of an epithelium is called what?

Explanation:
A localized shedding of the epithelium is erosion. This describes a shallow loss of the epidermis where only the surface layer of skin is removed, and the deeper dermal tissues remain intact. Because the injury is superficial, healing is typically quick and without scarring. An ulcer, in contrast, is a deeper defect that extends into the dermis or beyond, often with tissue loss and crater-like edges, which tends to heal with scarring. Dermatitis refers to inflammation of the skin, not a loss of epithelium, and xerosis means abnormally dry skin.
