Thyroid metastases from renal cell carcinoma

Abstract

Metastases to thyroid gland are a rare occurrence in surgical practice. The most frequent primitive tumor is renal cell carcinoma. We report a case of thyroid metastasis from renal cell carcinoma in a 70-year-old man who underwent left nephrectomy ten years earlier, presented with a diagnosis of multinodular goiter, associated with thyroiditis and right laterocervical lymphadenopathy. A total and the surgical excision of laterocervical lymph node were performed. The results, according to the histological examination, were metastases from renal cell carcinoma, involving both the thyroid gland and the lymph node. Therefore, since the delay of presentation and the difficulties of diagnosis, we recommend log-term follow-up of the head and neck region, for those patients with renal cell carcinoma diagnosis.
