Leiomyosarcoma of the renal vein is a rare tumor of complex diagnosis. We presented a case of renal vein leiomyosarcoma detected in a routine study. The primary treatment was complete surgical removal of the mass. In cases where surgical removal is not possible the prognosis is poor, with high rates of local recurrence and distant spread.
肾静脉平滑肌肉瘤是一种诊断复杂的罕见肿瘤。我们报告了一例在常规检查中发现的肾静脉平滑肌肉瘤病例。主要治疗方法是完整手术切除肿块。在无法进行手术切除的情况下，预后较差，局部复发和远处转移率较高。
