excoriation

n. harsh criticism

An excoriation is an erosion or destruction of the skin by mechanical means, which appears in the form of a scratch or abrasion of the skin. It is commonly seen in other skin disorders causing itching/pruritus: dry skin, dermatitis, atopic dermatitis, scabies, etc. The condition is characteristic of a symptom of other illnesses like liver failure where pruritus is caused by increases of bilirubin.
