Abstract
Despite thyroid is a highly vascularized organ, clinically significant metastatic spread to the thyroid is considered uncommon. There is a reported incidence of up to 24.0% metastases to the thyroid in autopsy series. The most frequently noted primary sites are the kidney, breast, and lung. The metastatic spread of alimentary tract is quite rare, and the majority comes from the colo-rectum. We present a case of squamous cell carcinoma of the cervical esophagus presenting as thyroid nodule in an apparently healthy 54 year-old male patient. This might be the first case of esophageal carcinoma metastases to the thyroid presenting in South Korea.
