Although peripheral blood eosinophilia is observed in patients with active inflammatory rheumatoid arthritis (RA), RA is not a recognised cause of pulmonary eosinophilia. We describe a 55-year-old woman affected by chronic eosinophilic pneumonia (CEP) concomitantly with an initiation of RA. Both diseases responded rapidly and completely to high-dose corticosteroid therapy. In this patient, the initiation of RA and CEP was directly related, implying a common pathogenetic link between the two diseases.
