Extraskeletal Ewing's sarcoma (EES) is rarely found in the head and neck region. We report here a case of EES of the parapharyngeal space in a 53-year-old man who presented with blurred vision, dysphagia, hoarseness and right facial numbness. CT examination showed a large, seemingly well-defined soft tissue mass in the right parapharyngeal space with skull base destruction and intracranial extension. The patient showed poor response to chemotherapy and radiotherapy and died 6 months after initial presentation. A review of the literature revealed no previous reports of EES occurring in the parapharyngeal space.
骨外尤文肉瘤（EES）在头颈部区域很少见。我们在此报告一例53岁男性发生于咽旁间隙的EES病例，该患者表现为视力模糊、吞咽困难、声音嘶哑和右侧面部麻木。CT检查显示右侧咽旁间隙有一个较大的、看似边界清晰的软组织肿块，伴有颅底破坏和颅内侵犯。该患者对化疗和放疗反应不佳，初诊后6个月死亡。文献回顾显示，此前尚无EES发生于咽旁间隙的报道。
