Laryngeal papilloma is a benign tumor characterized by minimal symptoms; however, in rare cases, it can cause airway obstruction and should be treated with caution. A 65-year-old woman presented to the clinic with a history of dyspnea for the past 20 years. Chest computed tomography revealed the presence of a tracheal diverticulum with an internal septum on the right side of the trachea at the apex of the lung. Upon examination, an otorhinolaryngologist revealed a wart-like tumor at the base of the tongue. However, it was ruled out to be the cause of dyspnea owing to the small size of the tumor. Thereafter, the patient was placed under observation. Brochoscopy was performed to investigate the tracheal diverticulum. Bronchoscopy revealed a pedunculated papilloma entering the glottis because of inhalation in the supine position, indicating a high risk of airway obstruction by the papilloma. The patient underwent papilloma resection. Papillomas must be considered in the differential diagnosis of dyspnea. The risk of airway obstruction should not be underestimated in patients with papilloma with reported history of dyspnea, even in the case of small tumors. The patient had a rare tracheal diverticulum, which further complicated the diagnosis of dyspnea.
