Lipoma.

A benign laryngeal tumor such as lipoma can sometimes develop airway stenosis. A 56-year-old woman with symptoms of pharyngeal discomfort and dyspnea in the supine position visited an ENT clinic and was diagnosed as having a laryngeal tumor. Endoscopic examination revealed that a space-occupying lesion between the base of the tongue and the epiglottis extended to the laryngeal cavity. Surgical resection was successfully completed without tracheostomy. General anesthesia was induced by nasal intubation assisted by nasal fiberscopy and transoral tumor retraction. Observation under a distending videolaryngoscope confirmed the tumor was raised from the epiglottis. Dissection of the tumor was achieved by fractional excision, and the tumor was diagnosed histologically as lipoma.
