Indapamide-induced pemphigus foliaceus.

A variety of drugs have been implicated to induce or trigger pemphigus. A case of pemphigus foliaceus that was probably caused by indapamide, in whom the diagnosis was based on clinical, histologic and direct immunofluorescence testing, is reported here. To the best of the authors' knowledge, this is the first reported patient with indapamide-induced pemphigus.
