Only a few cases of benign tumors in the larynx and hypopharynx have been reported in the literature. Benign tumors in this area can take prolonged courses and may cause serious consequences. This report discusses a case of pleomorphic adenoma of the larynx and a case of large hypopharyngeal lipoma both of which resulted in sudden airway obstruction.<br>Case 1 was a 47-year-old male who complained of a sore throat while swallowing. A yellow, large smooth tumor in the epiglottis expanding from glottic surface to laryngeal surface was revealed using fiberscopy. Immunohistochemistry of the biopsy specimen suggested the tumor was a pleomorphic adenoma, and subsequently a treacheostomy was performed to relieve the airway obstruction. The tumor was completely excised via a horizontal laryngectomy.<br>Case 2 was a 58-year-old female who experienced suffocation while eating. Fiberscopy showed a yellow, large smooth tumor expanding from hypopharynx to aryepiglottic fold. Biopsy and an emergency tracheostomy was performed. The tumor was removed completely via a lateral pharyngotomy approach. The 5.5×4.3×2.7cm tumor was pathologically diagnosed as lipoma, and was contained within the thyropharyngeal muscle, intramuscular type.
