[A resected case under thoracoscopic surgery of bilateral pulmonary metastases of renal cell carcinoma ten years after radical nephrectomy].

ABSTRACT

A 68-year-old male had received a left nephrectomy for renal cell carcinoma of the clear cell type in October, 1987. He had been given Interferon alpha (IFN alpha) for one year since then. He was referred to our hospital for bilateral abnormal shadows on the chest roentgenogram in December, 1997. He underwent a video-assisted thoracoscopic biopsy of bilateral lung in January, 1998, 11 years after his nephrectomy. The resected specimens contained a coin lesions measuring approximately 2 cm in diameter, and the lesions were microscopically diagnosed as a renal cell carcinoma of the clear cell type metastatic to the lung. The patient is doing well with no signs of re-recurrence five months after the resection of the metastatic lesion.
