A 70-year-old man underwent right nephrectomy for clear cell renal carcinoma in 1985. After nephrectomy, he was routinely followed up as an outpatient. Solitary chest tumor was detected on pulmonary CT in 2005. A wedge resection of pulmonary tumor was performed under diagnosis of primary lung cancer. The histological feature was not of primary lung cancer, but the previous nephrectomised specimen, i.e., clear cell renal carcinoma.
