title: [Metastatic renal tumor originating from esophageal cancer: report of 2 cases].
abstract: We report 2 cases of esophageal cancer metastatic to the kidney. The first case was in a 57-year-old man who complained of severe right flank pain. He had underwent an operation for esophageal cancer 2 months previously. A computerized tomography (CT) scan revealed a wedge-shaped, low-density mass in the right kidney. Right nephrectomy revealed squamous cell carcinoma. He has remained free of recurrence 3 months postoperatively. The second case was in a 57-year-old man with esophageal cancer treated by radiation therapy. Severe right flank pain and gross hematuria appeared after 1 year. A CT scan showed a wedge-shaped, low-density tumor in the right kidney accompanied with a tumor thrombus in the inferior vena cava. Right nephrectomy as well as resection of the thrombus were performed. Pathological diagnosis was squamous cell carcinoma. He died of cancer 2 months postoperatively.
