Thyroid metastasis of renal cell carcinoma. A case report.

In this article thyroid metastasis in a patient who was operated 11 years ago for renal cell carcinoma is reported with the review of the literature. That case was also the first and the only thyroid gland metastasis in 4.124 thyroidectomies during a 17-year period at our department. Because the thyroid gland may be the only and a rare metastatic site, differentiation of the metastatic lesion from the primary thyroid neoplasm could be difficult.
