Abstract：
The solitary fibrous tumor (SFT) is usually described as a lesion arising from the pleura. Rarely, it has been described in the parapharyngeal space (PS). This study aims to report two cases of SFT in the PS and to perform a literature review on this topic. Two patients undergoing surgical resection of a SFT in the PS, were reported. A literature review on SFT of the PS, was also performed. Two patients were analyzed. Both patients underwent surgical resection, followed by adjuvant radiotherapy, for SFT arising from the PS. The postoperative course was uneventful and both patients recovered well after the procedure. No recurrences were diagnosed during the followup. SFT of the PS is an infrequent entity. Surgical resection is the most used treatment, and adjuvant radiation should be considered in patients with recurrence risk factors or distant metastases.
摘要：
孤立性纤维瘤（SFT）通常被描述为由胸膜引起的病变。很少,已在咽旁间隙（PS）中进行了描述。本研究旨在报告PS中的2例SFT，并就此主题进行文献综述。两名患者在PS中接受SFT手术切除，被报道。关于PS的SFT的文献综述，也进行了。对2例患者进行分析。两名患者都接受了手术切除，其次是辅助放疗，对于由PS产生的SFT。术后病程顺利，两名患者术后均恢复良好。随访期间未确诊复发。PS的SFT是不常见的实体。手术切除是最常用的治疗方法，对于有复发危险因素或远处转移的患者，应考虑辅助放疗。
