[Thyroid metastasis of renal carcinoma]

Clinical detection of thyroideal metastasis of renal carcinoma is very rare; diagnosis of this type of metastasis is usually done at post-mortem examination. A case of thyroideal metastasis six years after nephrectomy due to renal carcinoma is presented. The slow evolution and good prognosis following surgical exercises justify an active therapy. Thirty-two months after the operation our patient is still free from the disease.
