[Angiosarcoma of the nasal cavity. Report of a case and review of the literature].

We report an unusual case of primary angiosarcoma of the nasal cavity (AS-nc). Clinical--monolateral epistaxis in a young person--, radiological--polypoid hemorrhagic tumor arising within the nasal cavity and expanding into paranasal sinuses--, pathological--a network of anastomosing channels and solid areas immunoreactive for CD31 and CD34--and prognostic features--patient alive and well 36 months after the original diagnosis--are superimposable to those of previously reported AS-nc, suggesting that this lesion should be considered as a peculiar variant of classical AS.
