<p>Lipomas in the head and neck region account for about 10% of all lipomas, but they are most often subcutaneous and are rarely located in the laryngeal cavity. Spindle cell lipoma (SCL) is a rare special type of lipoma. Herein, we report a case of pedunculated SCL of in the larynx.</p><p>A 52-year-old man detected to have a pedunculated mass in the upper esophagus visited our University hospital. The mass lesion had been detected several years earlier by upper gastrointestinal endoscopy, but the patient had no clinical symptoms. The mass lesion could not usually be seen by fiberoptic laryngoscopy. When the pharyngeal reflex was activated, the tip of the pedunculated mass was expelled into the pharyngeal cavity, and the base of the mass was confirmed in the left arytenoid region. The pedunculated mass was resected by transoral videolaryngoscopic surgery, and histological examination of the resected specimen revealed the diagnosis of SCL.</p><p>As recurrences and malignant transformation have been reported in cases of SCL, our patient remains under close follow-up.</p>
