A lung tumor was detected 2 to 9-months following nephrectomy. Preoperative diagnosis was pulmonary metastasis from renal cell carcinoma and pulmonary tumor resection was performed in each case. There was a 9- to 12-month interval between the detection and resection of the lung tumor. The histological diagnosis of the lung tumor in all three patient was pulmonary hamartoma. Following the resection of the lung tumor, recurrence was not noted in any of the patients.
