We report a case of renal metastasis from esophageal carcinoma. The patient was a 74-year-old man, who had undergone an operation for esophageal carcinoma thirteen months previously. He was admitted to our clinic for examination of a right renal mass. Computed tomography (CT) revealed an irregular low density area in the right kidney and angiography showed a hypovascular tumor. Partial nephrectomy was performed. Histological examination revealed squamous cell carcinoma and the diagnosis was metastasis of esophageal carcinoma. Metastatic renal tumors are rarely encountered clinically and, to our knowledge, the present case is only the 16th clinical report of the renal metastasis of esophageal carcinoma in Japan. However, metastasis to the kidney is relatively common at autopsy. It is the fifth most common site of metastasis following the lungs, liver, bones and adrenals. Consequently, patients with malignancy should be followed up while keeping renal metastasis in mind.
我们报告一例食管癌肾转移病例。患者为一名74岁男性，13个月前接受了食管癌手术。他因右肾肿物来我院检查。计算机断层扫描（CT）显示右肾有一不规则低密度区，血管造影显示肿瘤血供较少。行部分肾切除术。组织学检查显示为鳞状细胞癌，诊断为食管癌转移。临床上转移性肾肿瘤很少见，据我们所知，本病例是日本第16例食管癌肾转移的临床报告。然而，在尸检中肾转移相对常见。它是继肺、肝、骨和肾上腺之后第五常见的转移部位。因此，对恶性肿瘤患者进行随访时应考虑到肾转移。
