title: [Renal cell carcinoma metastatic to the base of tongue: a case report].
abstract: A 66-year-old male patient underwent left radical nephrectomy for stage III renal cell carcinoma (RCC) two years and eight months previously. He complained of discomfort at his pharynx. An otolaryngeal examination revealed a tumor about 1.3 cm in size at the base of tongue, and the tumor was resected. It was pathologically diagnosed as clear cell carcinoma and as tongue metastasis of RCC. The subsequent appearance of a minute pulmonary metastasis caused the administration of interferon-alpha and interleukin-II. At present, two years after the treatment, neither growth of lung metastasis nor recurrence of tongue tumor are noticed. Tongue metastasis of RCC is rare and its prognosis is poor. This is the 17th case reported in Japan.
