Angiosarcoma of the maxillary sinus

Angiosarcomas are rapidly growing malignant neoplasms arising from the vasc ular endothelial cells. Most common sites are the extremities and the retro peritoneal space, with only four per cent of angiosarcomas arising in the h ead and neck area, whilst the paranasal sinuses are one of the rarest locat ions. We report the case of a maxillary sinus angiosarcoma in a 72-year-old male patient. The first biopsy was inconclusive, whereas the second revealed an angiosarcoma. Medial maxillectomy was performed with subsequent external ir radiation.
