Necrolysis, toxic epidermal

A severe, blistering rash in which the surface layers of the skin peel off, exposing large areas of red raw skin over the body. The condition carries a risk of widespread infection and loss of body fluid and salts. The most common cause of toxic epidermal necrolysis is an adverse reaction to a drug, particularly a barbiturate, sulphonamide, or penicillin. The condition usually clears up when the drug is discontinued. Intravenous fluid replacement is sometimes necessary.
