Benign etiologies and primary thyroid cancers are the most common causes of incidental thyroid nodules. Clinically evident metastases to the thyroid gland are not common and account for 2%-3% of thyroid cancers, though the incidence of thyroid metastases reaches 24% in autopsy studies.¹ The most common clinically detected thyroid metastases originate from renal cell carcinoma (RCC; 48.1%).² We report here a rare case of a man with clear-cell RCC with late recurrence in the thyroid gland as a solitary metastasis, 13 years after the primary diagnosis.
