title: Quinidine-induced photosensitive livedo reticularis-like eruption.
abstract: A 39-year-old white man who was taking quinidine developed a purpuric eruption in a photodistributed livedo reticularis-like pattern. This is the fourth reported case of a similar eruption in patients taking quinidine. Possible pathophysiologic mechanisms for nonthrombocytopenic drug-induced purpuras are discussed.
