Metastatic tumors to the jawbones are uncommon. Metastatic lesions to the oro-facial region may be the first evidence of dissemination of an unknown tumor from its primary site. Follicular thyroid carcinoma rarely presents initially as a distant metastatic lesion within the mandible. This case of metastatic follicular thyroid carcinoma is presented to emphasize its unusual initial presentation within the body of the mandible, which mimicked an odontogenic tumor. It's important to detect the carcinoma early so that it can be treated successfully and also improves the prognosis of the patient. The histopathological features and immunohistochemical findings are also discussed.
