title: [A very rare case of low-grade angiosarcoma of the nose and paranasal sinuses].
abstract: Angiosarcomas of the nose and paranasal sinuses are extremely rare. Histologically angiosarcomas are divided into two groups: low and high-grade. We present a case of angiosarcoma of apparent low-grade malignancy localized within the nasal cavity and paranasal sinuses in a 74-year old woman treated by radiotherapy due to middle ear chemodectoma 21 years ago. She was surgically treated via the lateral rhinotomy. During the 23 months follow-up no recurrence or epistaxis have been observed.
