Hemangiopericytoma (HPC) is an exceedingly rare tumor of uncertain malignant potential. HPC is a vascular tumor arising from mesenchymal cell with pericytic differentiation. Most of the tumors have been reported in the extremities, retroperitoneum and skin. Occurrences of this tumor in the nasal cavity or paranasal sinuses are rare. Long term follow up is mandatory because the clinical and histological criteria for prediction of biologic behavior are imprecise. There are reports of recurrence and metastasis many years after radical resection. We report herein a case of sinonasal HPC, who presented in our department with a polypoid lesion blocking the right nasal cavity. The tumor was removed by wide surgical resection. The patient had norma...
