Liposarcomas are malignant mesenchymal tumours usually located in the retroperitoneum, rarely occurring as a single lesion in the kidney. We present a case of a 59-year-old male patient with a left renal mass detected by computed tomography scan. He underwent radical nephrectomy and the histopathological study reported a primary undifferentiated liposarcoma of the kidney without nodal involvement. After 15 months of surgery, he remained asymptomatic and without evidence of disease recurrence. The objective of this report is to present a case and literature review with current evidence of treatment options and prognostic factors for survival.
脂肪肉瘤是一种恶性间充质肿瘤，通常位于腹膜后，很少作为肾脏的单一病变出现。我们报告一例59岁男性患者，通过计算机断层扫描发现左肾肿物。他接受了根治性肾切除术，组织病理学研究报告为原发性未分化肾脂肪肉瘤，无淋巴结受累。手术后15个月，他仍无症状，无疾病复发迹象。本报告的目的是通过病例和文献回顾，提供目前关于治疗选择和生存预后因素的证据。
