[Pharyngeal metastasis and arteriovenous fistula of renal cell carcinoma--report of a case].
A 76-year-old Japanese male consulted our hospital complaining of dysphagia. He also complained of dyspnea, and a cardiovascular disorder was detected. Otolaryngological examination revealed dysphagia due to pharyngeal tumor. Further examination detected left renal cell carcinoma with multiple pulmonary metastasis, and selective angiography revealed arteriovenous fistula in the primary tumor. After resection of the pharyngeal tumor and left nephrectomy, pharyngeal tumor was pathologically confirmed as metastasis of renal cell carcinoma. Furthermore, after left nephrectomy, the cardiovascular disorder gradually improved. Thus, the cardiovascular disorder was considered to have developed based upon the arteriovenous fistulae. Pharyngeal metastasis of renal cell carcinoma is extremely rare, and the cardiovascular disorder in this case was also an extrarenal manifestation.
