Abstract
Introduction: We report A 53-year-old longstanding smoker and stonemason, who has been treated with methotrexate since 2017 for seropositive rheumatoid arthritis (RA), who presented to the emergency department of the Zuger Kantonsspital with cough, aching limbs and fever. During the investigations, bilateral apical pulmonary infiltrates and nodular changes were found. After extensive examinations, the diagnosis of Caplan syndrome was made.
