[Metastasis of renal carcinoma to the thyroid gland].
BACKGROUND
Intrathyroid metastases are uncommon. Clinically, the distinction may be difficult with thyroid malignant tumor.


METHODS
A 76-year-old woman was referred to our department for an evaluation of a dysphonia. She had a past history of renal cancer 6 months ago. A multinodular goiter was noticed at the palpation. Left recurrent laryngeal nerve palsy was observed; there was no cervical lymph node. Fine-needle aspiration was not contributive. Computed tomography confirmed the multinodular goiter. Total thyroidectomy was performed and final histologic examination revealed a metastasis of a renal cancer.


CONCLUSIONS
Even if intrathyroid metastasis are rare, the practitioner must suggest the diagnosis if the patient had a thyroid tumor and a past history of cancer. A fine-needle aspiration can help the diagnosis. The surgical management is recommended for isolated metastasis to the thyroid gland especially in renal cancer.
