Abstract
The kidney cancer’s thyroid metastases are very rare. The renal cancer is called the tumor of the "internist". The best
known of this cancer metastatic sites are the bone, the lymph nodes and the lung, while the thyroid metastases are rare.
We report on a 74-year-old man who consulted for a neck mass, dysphonia and dyspnea. The swelling of the thyroid gland was
visible. The clinical examination revealed a large goiter (13/9cm), painful, fixed and suspect with a collateral circulation. The
cervical ultrasound showed a basicervical mass and the cervical scintigraphy highlighted cold nodules. The thyroid fine needle
aspiration revealed metastasis from a renal carcinoma. The cervical-thoracic CT scan showed a right renal tumor, a left laterocervical
process and a mediastinal process with pulmonary nodules. A radical nephrectomy was performed and the histological exam showed
a tubulo-papillary carcinoma. The targeted therapy was introduced with a clinical and radiological partial response.
We highlight that a thyroid mass may be a metastasis which can be related to the evolution of a cancer that cannot be very frequent
such as the kidney’s carcinoma. The fine needle aspiration of the thyroid nodules greatly helps the balance sheet in search of the
primary tumor.

1 Introduction
The kidney cancer’s thyroid metastases are very rare. The renal cancer is well known for his unpredictable
evolution, it is called the tumor of the "internist". The best known of this cancer metastatic sites are the bone, the
lymph nodes and the lung, while the thyroid metastases are rare. The distinction between a metastasis and thyroid
malignancy by the clinical examination and the imaging is difficult, only the patient history can guide the
diagnosis to be affirmed by the histological examination.
2 Case Report
We report on a 74-year-old man who was treated for high blood pressure with a family history of breast cancer in
the sister. Our patient consulted for a neck mass with dysphonia and dyspnea (Figure 1).
