A case of retroperitoneal extraosseous Ewing's sarcoma (EES) with renal involvement, which simulated an exophytic renal mass, is reported. EES is a rare soft tissue tumor that can occur anywhere in the soft tissues, but is seen most commonly in the extremities. Although EES is histologically similar to osseous Ewing's sarcoma, it is usually found in older patients. EES should be included in the differential diagnosis of soft tissue tumors, especially in the second and third decade of life.
报告了一例伴有肾脏受累的腹膜后骨外尤文肉瘤（EES），其表现类似肾外生性肿块。EES是一种罕见的软组织肿瘤，可发生于软组织的任何部位，但最常见于四肢。尽管EES在组织学上与骨尤文肉瘤相似，但通常见于老年患者。EES应列入软组织肿瘤的鉴别诊断，尤其是在青少年时期。
