Pulmonary Nodulosis and Aseptic Granulomatous Lung Disease Occurring in Patients with Rheumatoid Arthritis Receiving Tumor Necrosis Factor-α-Blocking Agent: A Case Series

Abstract

Aseptic pulmonary nodular inflammation corresponding to rheumatoid nodules or noncaseating granulomatous inflammation can occur during anti-TNF-alpha therapy for RA, mainly etanercept. The mechanism explaining such a reaction is not clear but certainly includes different processes. These cases of pulmonary nodular inflammation generally have a benign course and do not systematically require withdrawal of treatment.
