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.
血管外皮细胞瘤（HPCs）/孤立性纤维性肿瘤是起源于血管的罕见肿瘤，发生于头颈部区域。这些肿瘤起源于毛细血管周细胞，难以与其他起源于血管的肿瘤相区分。HPC最初由Stout和Murray于1942年描述，通常发生在生命的第五个十年，占所有软组织肉瘤的3%-5%，所有血管肿瘤的1%。肿瘤通常发生在四肢、骨盆或头颈部区域；所有HPC中有15%-30%发生在头颈部。我们报告一例位于一名60岁男性右侧颊部区域的HPC病例。
