We present a relatively common tumor, Ewing's sarcoma, in an exceptionally rare site, the zygomatic bone, wherein the only symptom was swelling in the cheek despite intracranial extension. Ewing's sarcoma is not an uncommon tumor in the Asian Indian as it is in the African American. It appear to occur as frequently in the subcontinent as it does in Europe and in Americans of European descent.
我们报告了一例相对常见的肿瘤——尤因肉瘤，其发生在极为罕见的部位——颧骨，尽管肿瘤已侵犯颅内，但唯一的症状是脸颊肿胀。尤因肉瘤在亚洲印度人中并不像在非裔美国人中那样罕见。在印度次大陆，它的发病率似乎与欧洲以及欧洲裔美国人中一样高。
