Nasal haemangiopericytoma: report of two cases with literature review

Haemangiopericytoma (HPC) is a rare vascular tumour produced by proliferati on of pericytes. One hundred and thirty-three cases of HPC have been report ed in the nose and the paranasal sinuses. We present two more cases. Wide s urgical excision via lateral rhinotomy, midfacial degloving, or endonasal r emoval is the treatment of choice. Radiotherapy has been used post-operativ ely in cases of incomplete removal. Life-long follow-up is required to eval uate local recurrence and late metastases.
