Hemangiopericytomas (HPCs)/Solitary fibrous tumor are rare neoplasms of vascular origin that occur in head-and-neck region. These tumors arise from capillary pericytes and are difficult to distinguish from other tumors of vascular origin. HPC, initially described by Stout and Murray in 1942, usually occur in the fifth decade of life and account for 3%-5% of all soft-tissue sarcomas and 1% of all vascular tumors. The tumors usually occur in limbs, pelvis, or head-and-neck region; 15%-30% of all HPCs occur in head and neck. We report a case of HPC located in the right buccal area of a 60-year-old man.
