title: [Hemangiopericytoma of the maxillary sinus: apropos of a case].
abstract: Haemangiopericytoma is a rare vascular tumour arising from the proliferation of pericytes which are cells surrounding the capillaries. Since 1949 only 54 cases of haemangiopericytomas of the nose and paranasal sinuses have been reported in the literature. Of the latter, only 8 cases originated from the maxillary sinus. We report a further case originated from the maxillary sinus.
