초록
Laryngeal cysts are uncommon and account for approximately 5% of all benign laryngeal lesions. Airway obstruction associated with laryngeal cysts has rarely been reported in adults. We report the first case of a laryngeal cyst causing sudden airway obstruction in an adult patient with asthma. A 70-year-old man who had been recently diagnosed with asthma presented to an emergency room (ER) with sudden dyspnea and a choking sensation. These symptoms disappeared soon after arrival to the ER but recurred several days later, again spontaneously resolving without medication or further treatment. Interestingly, a pedunculated laryngeal cyst was diagnosed incidentally by esophagoduodenogastroscopy and was completely removed by CO2 laser. Laryngeal cysts should be considered in the differential diagnosis of patients with asthma who show the unusual symptoms of airway obstruction. (J Clinical Otolaryngol 2015;26:117-120)
