Angiosarcoma della cavità nasale. Descrizione di un caso e revisione della letteratura

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.
