Clavicle is a rare primary site for Ewing sarcoma (ES). We analyzed 4 patients with clavicular ES under our follow up and reviewed the literature on management of this rare tumor. All our patients were females with a median age of 16 years and were non metastatic at presentation. After a median follow-up of 21.5 months, 3 out of 4 patients are in complete remission. Clavicular ES in contrast to ES of other sites seems to have a female preponderance and outcomes are similar to non metastatic ES of other common sites.
锁骨是尤文肉瘤（ES）的罕见原发部位。我们分析了在随访中 4 例锁骨 ES 患者，并复习了关于这种罕见肿瘤治疗的文献。我们所有的患者均为女性，中位年龄 16 岁，初诊时无转移。中位随访 21.5 个月后，4 例患者中的 3 例完全缓解。与其他部位的 ES 相比，锁骨 ES 似乎女性发病倾向更高，且预后与其他常见部位无转移的 ES 相似。
