Endobronchial fibroepithelial polyp.

Benign airway tumors are rare and represent only 1.9% of pulmonary tumors. Fibroepithelial polyps are common benign lesions in the skin, uterus, and neck; however, it is rare in the tracheobronchial tree with only sporadic case reports. The etiology is unclear, but it is thought to be due to inflammation or infection, especially in smokers and in patients with chronic obstructive pulmonary disease. In this case report, we describe a rare case of endobronchial fibroepithelial polyp and the utility of an interventional endobronchial therapeutic approach.
