Hemangiomas of the maxilla and mandible are extremely rare, although they probably occur more frequently than the number of reported cases would indicate. There are both capillary and cavernous types, the cavernous variety having been reported more frequently. This condition is extremely serious in the jaw bones, not only because of the frequent exposure of these bones to trauma but also because their close relation to teeth may necessitate extraction. The simple procedure of tooth extraction or biopsy may have a fatal ending. In several instances the condition was not suspected, and the profuse exsanguinating hemorrhage which followed tooth extraction made the diagnosis obvious. Deaths have been reported from lesions in the maxilla as well as in the mandible and from lesions of both the capillary and the cavernous types. In the majority of reported cases, the lesions have been relatively small, very cellular, and not attended by profuse hemorrhage.
