A case of acute (toxic) epidermal necrolysis is reported in the dental literature for the first time. This severe, life-threatening mucocutaneous syndrome resembles severely scalded skin. Sloughing vesiculobullous oral lesions are a frequent component. Staphylococcus aureus and drug reactions may cause separate entities presenting clinically as acute epidermal necrolysis. This case of drug-induced epidermal necrolysis in a child was successfully treated with methicillin and hydrocortisone.
