[Pleuro-pericarditis developed under a leflunomide therapy]

Abstract

Leflunomide is an immunosuppressant drug used in rheumatoid arthritis and psoriatic arthritis. This product may cause rare but serious interstitial lung disease that appear at the beginning of treatment. This is why leflunomide should be prescribed and monitored in hospital. We present the case of a 71 years old woman who presented a pleuro-pericarditis with an increase of CA 125 during a treatment with leflunomide. This is the second case reported in the literature. The outcome was favorable after discontinuation of leflunomide.
