title: Photoallergy induced by quinidine.
abstract: An 82-year-old woman presented with a lichenified dermatitis over light-exposed areas. The eruption cleared upon withdrawal of quinidine and recurred on re-administration of the drug. Though quinidine has not been recognized as a photo-sensitizing agent, upon review of the literature we have uncovered other cases which meet the criteria and justify including this drug among those capable of causing such reactions.
