Abstract
Malignant tumors are able to grow at sites distant from the primary site of origin. Breast, prostate, renal, thyroid, and lung carcinomas commonly metastasize to bone. Jaw metastasis is rare but may occur more often than generally estimated. Follicular carcinomas of the thyroid gland are tumors of follicular cell differentiation that consist of a microfollicular architecture with follicles lined by cuboidal epithelial cells. It is very difficult to diagnose this type of cancer at the preoperative or intraoperative stage of treatment. Here, we report a case of follicular carcinoma of the thyroid gland who was referred due to a mandibular lesion.
