Ewing sarcoma is a small round cell tumor of uncertain differentiation, primarily originating in bone in children and adolescents. Ewing sarcoma of the kidney is a rare occurrence and follows an aggressive course with early metastasis. Herein, we present a case of a 16-year-old male presenting with abdominal pain and lump. He underwent nephrectomy and histopathological diagnosis of small round cell tumor with differential diagnosis of Ewing sarcoma was made which was further confirmed by immunohistochemistry. Thus, Ewing sarcoma must also be taken into consideration while dealing with tumors of the kidney in young age group.
尤因肉瘤是一种分化不明的小圆细胞肿瘤，主要起源于儿童和青少年的骨骼。肾尤因肉瘤极为罕见，病程进展迅速，早期即可发生转移。在此，我们报告一例16岁男性患者，因腹痛和肿块就诊。他接受了肾切除术，组织病理学诊断为小圆细胞肿瘤，鉴别诊断为尤因肉瘤，免疫组化进一步证实。因此，在处理年轻患者的肾脏肿瘤时，也必须考虑到尤因肉瘤。
