title: [Metastatic renal tumor originating from esophageal carcinoma: a case report].
abstract: A 61-year-old male, who had undergone operation of esophageal carcinoma 11 months earlier, was admitted for left flank pain and high fever. Intravenous pyelography showed a space occupying lesion in the upper half of the left kidney. Computed tomographic scan showed an irregular low density area in the upper half of the left kidney. Angiograms revealed a hypovascular mass with encasement vessels in the same site. Left nephrectomy and paraaortic lymph node biopsy was performed. Pathological examination revealed a metastatic squamous carcinoma from the esophageal carcinoma. Chemotherapy was conducted, but he died 2 months later. Autopsy revealed recurrence in the retroperitoneum, and no metastasis in the right kidney. The literature on secondary renal tumor is reviewed.
