[Renal cell carcinoma metastasis to the thyroid gland 15 years after nephrectomy]

Abstract

Renal cell carcinoma (RCC) metastasis to the thyroid gland is rare and can mimic primary thyroid carcinoma leading to diagnostic difficulties. We present a case of a 55-year-old female with RCC metastasis to the thyroid gland 15 years after nephrectomy. Diagnosis was made after total thyroidectomy. This case emphasizes the importance of considering metastasis in patients with increasing growth of the thyroid gland over a short period of time known with earlier RCC, even decades after nephrectomy.
