Current Concepts of Toxic Epidermal Necrolysis

Toxic epidermal necrolysis consists of two distinct clinical entities. The Ritter type, seen mostly in children under age 10, is the severest manifestation of staphylococcal disease. A toxin has been isolated which is postulated to be the cause for clinical lesions. High epidermal necrosis occurs. Treatment is with one of the penicillinase-resistant pencillins, and prognosis is good. The Lyell type is seen mostly in adults, is drug-related, and may be the severest form of the Stevens-Johnson syndrome. Full-thickness epidermal necrosis occurs. Treatment consists of withdrawing the offending drug. Good nursing care is essential. Prognosis is guarded.
