Abstract

More than 100 cases of sinonasal hemangiopericytoma have been reported in the literature, but only a handful of cases of nasal glomangiopericytoma. In this article, we report a case of a nasal glomangiopericytoma that was treated with endonasal surgical excision. We also attempt to clarify the confusion that attends to the nomenclature surrounding the terms glomangiopericytoma and hemangiopericytoma, which are often used interchangeably. Although glomangiopericytomas are histologically similar to sinonasal hemangiopericytomas, they sometimes behave in a different clinical manner. To further enhance our understanding of nasal glomangiopericytomas, more cases need to be reported. This may improve our ability to establish specific treatment modalities for this type of neoplasm and to predict clinical outcomes.
