Mounier-Kuhn syndrome is a relatively rare condition, mostly involving the trachea and main stem bronchi. It is caused either by the atrophy of elastic fibers or faulty fetal development of cartilage and smooth muscles, hence leading to an overall increase in the diameter of lower respiratory tract. No certain etiology was found in the majority of cases reported previously, however, several other connective tissue diseases have also been implicated with the congenital tracheobronchomegaly. One anecdotal case report mentioned the development of lung malignancy in a patient who had previously received external beam radiotherapy. Herein, we report the first case of Mounier-Kuhn syndrome in a 62-year-old male with a recent diagnosis of metastatic squamous cell carcinoma (SCC) of the lung.

Mounier-Kuhn syndrome, also known as tracheobronchomegaly, is a rare clinical and radiological condition characterized by tracheobronchial dilatation and recurrent respiratory infections. Patients may be asymptomatic or present with severe respiratory illnesses. A CT scan is sufficient to confirm the diagnosis.

Mounier-Kuhn syndrome (MKS) or tracheobronchomegaly is an uncommon disease of the central airways. It is characterized by pathological dilatation of the trachea and main bronchi and inevitably leads to recurrent respiratory infections, bronchiectasis, hospitalizations, and results in considerable morbidity and mortality. Despite numerous case reports, there is a shortage of evidence on clinical outcomes and limited data on interventions, thus presenting a significant gap in the literature.

Tracheobronchomegaly (TBM) is a rare condition characterized by the dilatation of the trachea and bronchi due to severe atrophy of elastic fibers, accompanied by the thinning of the muscularis mucosae and the development of diverticula between cartilaginous rings. The etiology of this condition remains unclear. Tracheobronchopathia osteochondroplastica (TO) is another uncommon airway disease with an unknown etiology.
