Abstract：
Ewing\'s sarcoma is generally observed in the skeletal and connective tissues of paediatric individuals. The occurrence of extraosseous neuroectodermal tumours is uncommon. Renal Ewing\'s sarcoma usually presents with flank pain, haematuria, or as an abdominal mass. Immunohistochemistry and fluorescence in situ hybridization (FISH) techniques are essential in its diagnosis and differentiation from other tumours. We present asymptomatic renal Ewing\'s sarcoma in a 19-year-old female patient who was diagnosed incidentally, and the CT scan confirmed a 2.8 cm left mid-pole renal mass suggestive of malignancy. She was managed with a robotic partial nephrectomy. Tumour immunohistochemistry and the FISH technique confirmed the diagnosis of Ewing\'s sarcoma. The patient made an uneventful recovery and was referred for chemotherapy. This case report illustrates that despite the aggressiveness of the tumour, it can be detected earlier despite an asymptomatic presentation and be successfully treated with nephron-sparing surgery and chemotherapy.
摘要：
尤因肉瘤通常在儿科个体的骨骼和结缔组织中观察到。骨外神经外胚层肿瘤的发生并不常见。肾尤文肉瘤通常表现为侧腹疼痛，血尿,或者作为腹部肿块。免疫组织化学和荧光原位杂交（FISH）技术对于其诊断和与其他肿瘤的区分至关重要。我们介绍了一名19岁女性患者的无症状肾尤因肉瘤，CT扫描证实左中极肾肿块2.8厘米，提示恶性肿瘤。她接受了机器人部分肾切除术。肿瘤免疫组织化学和FISH技术证实了尤因肉瘤的诊断。患者恢复顺利，并接受化疗。该病例报告表明，尽管肿瘤具有侵袭性，尽管无症状表现，但仍可以更早发现，并且可以通过保留肾单位的手术和化学疗法成功治疗。
