title: Metastatic thyroid carcinoma.
abstract: Although metastases to the thyroid gland are common in autopsy studies, clinically significant metastases are rare. A 58-year-old Turkish patient, presenting with thyroid metastasis 2 years after undergoing left nephrectomy for renal cell carcinoma, is reported in this case report. Thyroid metastasis can be the initial presentation of renal cell carcinoma, or it may occur a long time after nephrectomy, which can lead to misdiagnosis of primary thyroid neoplasm. Radiographic features are not useful in making discrimination between the two, however a fine needle aspiration biopsy can be useful. The role of surgical therapy is controversial.
