Reported is the case of an esophageal cancer presenting a renal metastasis, which was detected and resected as the only recurrent focus. The patient was a 62-year-old male. Five months after an esophagectomy, a left renal mass was detected by abdominal computerized tomography, and a rise in the SCC antigen. The urinary cytology suggested a renal metastasis of the esophageal cancer. Thus, chemotherapy and irradiation was performed, followed by a resection. The histology of the resected mass showed a squamous cell carcinoma, similar to the findings at the primary site. A renal metastasis of an esophageal carcinoma usually is latent, but not rarely found on postmortem examination. A nephrectomy for a renal metastasis of an esophageal cancer is rare, and only 8 cases are reported in the literature.
报告了一例食管癌出现肾转移的病例，该转移灶作为唯一的复发灶被检测到并切除。患者为62岁男性。食管切除术后五个月，腹部计算机断层扫描检测到左肾肿块，同时鳞状细胞癌抗原（SCC抗原）升高。尿液细胞学检查提示为食管癌肾转移。因此，先进行了化疗和放疗，随后进行了手术切除。切除肿块的组织学检查显示为鳞状细胞癌，与原发部位的表现相似。食管癌的肾转移通常是隐匿性的，但在尸检中并不少见。因食管癌肾转移而行肾切除术很少见，文献中仅报道了8例。
