Abstract
The most common endocrine cancer is thyroid carcinoma, however it seldom spreads to the oral cavity. Follicular thyroid carcinoma is the second most common type of thyroid cancer after papillary thyroid carcinoma. Thyroid carcinoma-related mandibular metastases is not very common, and there aren't many cases reported in the literature. We are describing a case in which the underlying cancer was diagnosed before the metastatic mandibular lesion was found. Total thyroidectomy and excision of the affected structures, with or without adjuvant therapy, appear to be the most effective treatments.
