[Drug-induced pemphigus].

A review of the literature on previous cases of drug-induced pemphigus as well as two case reports of pyritinole-induced pemphigus show a few characteristics: D-penicillamine was responsible in 42 cases, pyritinole in 4 cases, the two case reports included. Superficial pemphigus was seen in about 75% of the cases, most times associated with preexistent autoimmunological disorders. Immunological findings were identical with normal, non-drug-induced pemphigus, while the prognosis was better under mostly necessary immunosuppressive therapy at relatively low doses.
