[Allergic vasculitis following ingestion of celecoxib?]

A 76-year-old patient developed cutaneous vasculitis on the lower legs on the 8th day of treatment with the selective cox-2-inhibitor celecoxib (Celebrex((R))) and the proton-pump inhibitor omeprazole. The patient had no history of allergic reactions. The patient had already been treated previously with omeprazole without any side effects. A cutaneous biopsy confirmed the diagnosis of leucocytoclastic vasculitis. The purpuric skin lesions regressed within 3 weeks after withdrawing the two newly introduced drugs. We discuss the potential role of Celecoxib in triggering this vasculitis.
