A 64-year-old man was referred to our hospital for the treatment of left renal cell carcinoma associated with a tumor located on the back of the inferior vena cava. At first the tumor located on the back of the inferior vena cava was suspected to be lymphnode metastasis of renal cell carcinoma. A more detailed examination at our hospital revealed elevation of vanillylmandelic acid in urine and (131)Imetaiodobenzylguanidine uptake in the tumor. We diagnosed the tumor as paraganglioma and operated both tumors at the same time. Histological examination revealed chromophobe renal cell carcinoma and paraganglioma. His important to discriminate paraganglioma in the renal cell carcinoma that has an atypical swelling of lymphnode.
一名64岁男性因治疗左肾细胞癌伴下腔静脉后方肿瘤而转诊至我院。起初，怀疑下腔静脉后方的肿瘤是肾细胞癌的淋巴结转移。我院更详细的检查发现尿香草扁桃酸升高以及肿瘤对（131）I-间碘苄胍摄取。我们将该肿瘤诊断为副神经节瘤，并同时对两个肿瘤进行了手术。组织学检查显示为嫌色肾细胞癌和副神经节瘤。鉴别肾细胞癌中出现非典型淋巴结肿大的副神经节瘤很重要。
