A 66-year-old man first underwent total nephroureterectomy for transitional cell carcinoma of the renal pelvis. A solitary pulmonary metastasis developed 2 years subsequent to the initial operation. A middle pulmonary lobectomy was performed and the histological diagnosis was metastatic transitional cell carcinoma. At the present time, 5 years after removal of the solitary pulmonary metastasis, this patient is apparently free of tumor.
