Abstract Previously, cases of metastatic thyroid cancer were only identified following mortality, by autopsy studies. Incidence of this disease is currently estimated to be between 0.5\% in all malignant tumors and 24\% in all patients based on autopsy studies. Metastatic thyroid cancer is associated with poor prognosis. In the present study, a 58-year-old male presented with a cervical mass. Subtotal gastrectomy and D2 lymph node dissection identified a poorly differentiated gastric adenocarcinoma. Following this, fine needle aspiration was performed, revealing that the thyroid tumor cells were similar to gastric tumor cells, indicative of metastasis from this organ of origin. In addition, immunohistochemical analysis was consistent with this diagnosis. Palliative radiotherapy of the thyroid mass was performed. At manuscript submission, the patient remained alive.
