A dramatic case of oral epitheliolysis

Oral epitheliolysis or mucosal shedding is an infrequently described phenomenon characterized by epithelial desquamation, revealing mucosa of normal color and texture underneath. The condition has a predilection for middle-aged females and primarily affects nonkeratinized oral tissues. Although some cases are idiopathic, certain oral hygiene products have been implicated as the culprit, and resolution of the condition documented with their discontinuation. Severity of desquamation and symptoms vary with frequency and duration of contact with the irritant and its concentration. A case is presented of a dramatic case of shedding oral mucosa in an elderly female, which appeared to be caused by habitual chewing of an aspirin-containing over-the-counter analgesic.
