Drug-induced linear immunoglobulin A bullous disease that clinically mimics toxic epidermal necrolysis

Drug-induced linear immunoglobulin A bullous disease is a subepidermal blis tering disorder that most commonly occurs after exposure to vancomycin. It can clinically mimic toxic epidermolyic necrolysis. We describe an 87-year- old white woman in whom linear immunoglobulin A bullous disease developed w hile she was taking vancomycin and phenytoin. A few days after the linear i mmunoglobulin A bullous disease developed, both medications were discontinu ed. No new bullae developed, and the eruption completely resolved within 2 weeks. The patient was treated with only topical therapy.
