title: [An esophageal cancer with a renal metastasis that was detected and resected as the only focus of recurrence].
abstract: 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.
