Hemangiopericytoma of the parapharyngeal space.
Hemangiopericytomas of the head and neck are rarely found in the parapharyngeal space. We report the case of a 53-year-old woman who presented with a globus sensation in her throat. Imaging detected a left submucosal oropharyngeal mass that extended into the prestyloid parapharyngeal space. The tumor was surgically excised en bloc. Histopathologic examination identified it as a hemangiopericytoma. We discuss the diagnosis and management of this rare entity.
