Flexible bronchoscopy identified an oval, hard foreign body lodged in the bronchus, which was successfully removed using biopsy forceps. The extracted object was confirmed to be a mukago. His cough disappeared after removal. Our case highlights the importance of considering foreign body aspiration in elderly patients presenting with unexplained chronic cough, even in the absence of overt choking episodes. Thorough dietary history\u2010taking, appropriate imaging, and bronchoscopy are essential for timely diagnosis and effective management of foreign body
