Angiosarcomas of the head and neck are rare tumors, the intra-oral localization being considered exceptionally in the specialty literature. The diagnosis of this kind of tumor is difficult, both to the rarity of this lesion at this site, and to the various histopathological aspects. We present the case of 70-year-old male patient clinically diagnosed with tumor of the alveolar crest of mandible, which, histopathologically, associated areas of predominant vascular proliferation, with areas of carcinoma and sarcoma. Immunohistochemical, the tumor was investigated for CD31, AE1-AE3 and vimentin.
