Background and clinical significance Squamous cell metaplasia (SCM) is a reversible process in response to chronic injury. While SCM is a standard response to irritation in the proximal bronchi, its occurrence in the distal, non-cartilaginous bronchioles is significantly less common and reflects remarkable epithelial plasticity. In the distal airways, true SCM is rare and typically associated with specific pathologies such as granulomatous inflammation. This case highlights SCM within the bronch
