METHODS: A 49-year-old man was admitted to our ENT outpatient clinic with a chief complaint of pharynx discomfort for 2 months. Laryngoscopy performed under topical anesthesia revealed a solitary, pink mass at the tubercle of epiglottis. Surgery via laryngeal endoscopy was performed under general anesthesia, and the lesion was excised easily. Positive immunohistochemical staining for desmin and smooth-muscle actin indicated a smooth muscle origin and the diagnosis was laryngeal leiomyoma. After surgery, the patient\'s condition was stable, and he was discharged 2 d after surgery. During the 1-year postoperative period, the patient\'s condition remained stable without evidence of recurrence.
CONCLUSIONS: Surgical resection is the preferred treatment for LLMs, its early diagnosis and differential diagnosis have important clinical significance.
