We report two cases of laryngeal hemangioma. The first case was a 32-year-old female. She complained of dyspnea while lying down and an abnormal sensation on swallowing. From the laryngoscopic findings showing a large dark red tumor located from the right false vocal cord to the piriform recess, we suspected laryngeal hemangioma. After MRI, angiography and embolization, we resected the tumor by lateral pharyngotomy with a tracheotomy. The second case was a 19-year-old male complaining of a swollen neck and an abnormal sensation in the larynx. He also had a large hemangioma located from the right false vocal cord to the pharynx beyond the piriform recess. His tumor was resected by the same method. Both tumors were revealed to be cavernous hemangioma by histological examination. Although several treatment methods for laryngeal hemangioma are known, it is preferable for a large tumor to be resected by lateral pharyngotomy or lateral laryngotomy, becouse it can be resected more safety under a wide view.
