Metastatic tumors to the oral cavity affecting either the jaws or the soft tissue are unusual and accounts approximatively for 1% of all oral malignant neoplasms. Morever, a thyroid primary tumor is considered almost rare. The present paper describes a case of metastatic follicular thyroid carcinoma to the right maxillary sinus, bone and alveolar mucosa in a 73-year-old male patient. Our aim is to highlight the importance of considering oral metastasis in the diagnosis of jaws and soft tissue lesions especially in patients with known primary malignant tumor.
