[Pemphigus foliaceus caused by penicillamine]

We report the case of an 80-year-old woman who developed pemphigus foliaceus while taking penicillamine for rheumatoid arthritis. On the basis of this new case, we discuss fresh insights into the pathogenesis of drug-induced pemphigus. In addition, having reviewed the literature, we give a list of drugs that have been reported to induce this disease.
