title: Thrombocytopenic purpura secondary to quinidine hypersensitivity.
abstract: A case of quinidine-induced thrombocytopenic purpura is reported. The patient had been previously sensitized and developed oral bleeding. On repeated ingestion of the drug, he developed classic oral manifestations of the hemorrhagic disease and sought dental treatment. Identification and withdrawal of the drug reversed the clinical and hematologic symptoms.
