A case of laryngeal hemangioma is reported. On esophagogastroduodenoscopy, a 67-year-old man demonstrated a dark red mass in the larynx and was referred to our clinic. Fiberscopic examination showed the presence of laryngeal hemangioma in the left false vocal cord extending to the piriform sinus. CT and MRI findings were compatible with those of laryngeal hemangioma; however, the feeding artery was not detected by angiography.After performing tracheostomy under local anesthesia in order to secure the airway and obtain a good surgical field, the tumor was vaporized with CO2 laser under laryngo-micro-surgery and injected with 5% ethanolamine oleate, a sclerosing agent which has been used endoscopically in the treatment of esophageal varicus.One day after the surgery, a severe edema in the larynx was observed. However, the tumor size gradually reduced day by day and was localized in the left arytenoid three weeks after surgery.
