A 62-year-old male, who had undergone right nephrectomy to treat renal cancer 19 years earlier, was recently referred to our hospital to receive a detailed examination and treatment of mediastinal lymph node swelling. Biopsy of the swollen lymph nodes allowed a diagnosis of renal cell carcinoma (alveolar type, clear cell subtype, GI) to be made. The pathological features of his tumor were consistent with those of the renal tumor resected 19 years previously. Because there was a high probability of further growth of the swollen mediastinal lymph nodes and consequent high probability of compression of the superior vena cava, we performed mediastinal lymph node excision. Immediately after surgery, prophylactic interferon therapy was started. To date, five cases (including the present case) in which renal tumors recurred more than 15 years after surgical treatment have been reported in Japan.
一名62岁男性，19年前因肾癌接受了右肾切除术，最近转诊至我院接受纵隔淋巴结肿大的详细检查和治疗。对肿大淋巴结进行活检后诊断为肾细胞癌（肺泡型，透明细胞亚型，GI）。其肿瘤的病理特征与19年前切除的肾肿瘤一致。由于肿大的纵隔淋巴结很可能进一步生长，进而压迫上腔静脉的可能性很大，我们进行了纵隔淋巴结切除术。手术后立即开始预防性干扰素治疗。迄今为止，日本已报道了5例（包括本病例）肾肿瘤在手术治疗15年以上后复发的病例。
