%X <B>BACKGROUND: </B>Leiomyomas (LMs) are mesenchymal tumors that arise from smooth muscle cells. LMs most commonly arise in organs with an abundance of smooth muscle such as the uterus and gastrointestinal tract. Conversely, LMs are rarely detected in the head and neck region. In this study, we report a rare case of laryngeal LM (LLM) and summarized the clinical characteristics of reported LLMs to help clinicians better understand this rare disease and improve its diagnosis, treatment, and postoperative course.<BR><B>METHODS: </B>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.<BR><B>CONCLUSIONS: </B>Surgical resection is the preferred treatment for LLMs, its early diagnosis and differential diagnosis have important clinical significance.
