title: Procainamide-induced urticarial vasculitis.
abstract: Dermatologists are often faced with the difficulty of evaluating drug reactions in patients receiving multiple medications. Unfortunately, few drugs produce distinctive lesions; many types of medications can produce identical eruptions. One common drug-induced eruption is urticaria. We report a specific eruption due to procainamide: urticarial vasculitis.
