The incidence of renal metastasis in lung cancer, the most common neoplasm to metastasize to the kidneys, is about 19% at autopsy. However, antemortem diagnosis of renal metastasis is not common. A rare case of gross hematuria caused by a biopsy-proven renal neoplasm that metastasized from an esophageal carcinoma is reported here by Dr Sivarajan and associates.
