Isolated thyroid metastasis from renal cell carcinoma

Özet

Metastatic neoplasms of the thyroid are uncommon when compared to primary tumors of the gland. Renal cellcarcinoma (RCC) is a highly aggressive tumor of the urinary system. It can spread all over the body. Isolated solitarymetastases of RCC to the thyroid are very rarely observed. A 64-year-old woman with a history of left radical nephrectomy for RCC, was referred to our clinic with palpable thyroid nodule. Ultrasound confirmed the nodule onthe left lobe. Histopathological examination of the thyroidectomy specimen revealed that there were two solitarymetastasis of RCC. No other distant metastasis were detected. Metastatic tumors of the thyroid gland are very rare.When patients with thyroid nodule are referred to our clinic with the history of other malignancies, we must consider metastasis. Thyroidectomy is recommended in the case of isolated thyroid metastasis of RCC.
