Haemangiopericytoma of the nose and paranasal sinuses.
The uncertain course and rarity of haemangiopericytoma in the nose and paranasal sinuses has interested both pathologists and clinicians. This tumour arises from proliferation of pericytes which invest capillary endothelium. A benign course is more common in the nose and paranasal sinuses. The first nasal haemangiopericytoma was reported by Stout in 1949. Since then only twenty cases have been reported in the literature. We present three further cases.
