Vasculitis associated with the use of leflunomide.
Vasculitis as a complication of leflunomide therapy in the treatment of rheumatoid arthritis has been reported. We describe a case of acute necrotizing vasculitis following leflunomide therapy. Characteristics of this case and 4 cases in the literature suggest that vasculitis may be a rare but serious adverse effect of leflunomide therapy.
