Renal angiomyolipoma, a benign tumor, can involve regional lymph nodes. Although this phenomenon has been reported previously followup information has been scant. We have treated 3 patients who had renal angiomyolipoma with nodal involvement and all had further evidence of tuberous sclerosis. Each patient had hematuria with flank pain and required nephrectomy. In the ensuing 3 to 11 years none of these patients has had evidence of further disease progression. Nodal involvement may reflect the multicentricity of angiomyolipoma or may represent a form of "benign metastasis" but it does not appear to be a harbinger of disease progression.
肾血管平滑肌脂肪瘤是一种良性肿瘤，可累及区域淋巴结。尽管此前已有相关报道，但随访信息较少。我们治疗了3例伴有淋巴结受累的肾血管平滑肌脂肪瘤患者，所有患者均有结节性硬化症的进一步证据。每位患者均有血尿伴侧腹痛，需要进行肾切除术。在随后的3至11年里，这些患者均无疾病进一步进展的迹象。淋巴结受累可能反映了血管平滑肌脂肪瘤的多中心性，也可能代表一种“良性转移”形式，但它似乎并非疾病进展的先兆。
