Metastases to the thyroid gland-a report of six cases.
The association of an asymptomatic mass, normal thyroid function, and a cold nodule can occur months to years after a primary cancer. Work-up should include ruling out other metastases and fine-needle aspiration cytology. We report six cases of secondary thyroid cancer. Two of the patients in our series presented with hyperthyroidism, which may be due to invasion and disruption of thyroid follicles.
