The types of treatment for hemangiomas occurring around or within the oral cavity are discussed. Excision of smaller, totally accessible vascular tumors is advised. The more obscure, larger, or deeper tumors may be better treated by sclerosing solution injections. Four cases of hemangioma are presented. One case, because of the inadvertent injection of a radiopaque contrast medium into the afferent vessel of the tumor, was made radiographically visible. The effectiveness of injections of a sclerosing solution could now unmistakably be calculated and visualized. Two other cases of oral hemangioma were treated by injections of the sclerosing solution. All three patients were relieved of their tumors. One patient's hemangioma was treated by total excision. No recurrence was found in any of these cases. It is suggested that these two methods of treatment be given priority over radiation therapy in other cases of a similar nature.
