Mandibular metastasis from thyroid follicular carcinoma: A case report

Abstract

The authors report a case of right mandibular metastasis from thyroid follicular carcinoma of a 71-year-old woman who suffered from painless swelling in the right retromolar region for 10 months. As pulse was detected through a mass, we suspected that the mass was hemangiosarcoma or A–V malformation. However, by an incisional biopsy, a diagnosis of a metastasis from thyroid follicular carcinoma, was suggested. Under general anesthesia, right lobe thyroid gland resection, mandible segmental resection, neck dissection, and plate reconstruction were performed. Final diagnosis of thyroid follicular carcinoma and metastasis to the right mandible was made. The postoperative period was uneventful and the patient was asymptomatic without signs of recurrence 4 years postoperatively. The present case is the uncommon case of mandibular metastasis from thyroid follicular carcinoma.
