Abstract

A case of hemangiopericytoma-like tumour (HPCLT) of the nasal cavity is described in a 81-year-old woman. The tumour, accompanied by symptoms of nasal obstruction and epistaxis, presented as a polypoid lesion filling the left middle meatus region. Histological, immunohistochemical and electron microscope studies revealed a uniform sheet-like proliferation of spindle to oval vimentin-positive cells growing around a rich vascular network. The favourable outcome sixteen months after endoscopic sphenoethmoidectomy would seem to confirm the diagnosis of HPCLT. The differential diagnosis of this rare lesion is discussed.
