We here report one case of tracheobronchopathia osteochondroplastica. Case Report: A 64-year-old female patient was admitted to the hospital with a productive cough, sputum, and fever for ten days. Her chest CT scan showed mild thickening and irregularity associated with calcification in the trachea wall and main bronchus. The patient had rheumatoid arthritis, and after consultation with a rheumatologist, she received pneumonia treatment and then underwent bronchoscopy. Conclusion: TPO is a rare, benign disease with slow progression. Physicians should be aware of TPO and should consider it in patients with chronic cough and respiratory infections. https://crcp.tums.ac.ir/index.php/crcp/article/view/258 https://crcp.tums.ac.ir/index.php/crcp/article/download/258/337
