The objetive of this paper is to expose our experience in the surgical treatment of an arteriovenous fistulae of the lower lip in 15 years- old patien, caused for humanbite. The patient was first diagnosed as traumatic hemangioma, treated with steroids and surgical removal. Four years later a voluminous tumor appeared, a dissection of the external carotid and a carotid angiography was performed and an arteriovenous fistulae was diagnosed. A ligament of the facial and venous vasseles was performed to isolete them from circulation. 4cc of Betametaza were inyected inside of tumors, and later 4 additional doses with 3 week of interval. Three months after the ligament a surgical removal of the fibrous tumor was done. At present, after 5 years of the last operation, the patient is getting well, with no recidive. The importance of the angiography study has been put into evidence, to diagnose and treat this athology, which is not so common.
