Hemangiopericytoma (Solitary fibrous tumor) of parapharyngeal space: A rare tumor

Abstract Tumors of parapharyngeal space are difficult to access for clinical examination, due to critical location of this anatomic area. Most of these tumors are benign. Hemangiopericytomas arising in parapharyngeal space are extremely rare tumors and they have uncertain malignant potential. Radical excision of tumor is the treatment of choice. Here we report a case of young adult male patient who presented with very nonspecific throat symptom and on clinical and radiologic evaluation diagnosis of pre-styloid parapharyngeal space tumor was made and post-surgical histopatholology report showed hemangiopericytoma (solitary fibrous tumor).
