Abstract
Thyroid carcinomas are usually classified as papillary thyroid carcinoma, follicular thyroid carcinoma, medullary thyroid carcinoma and anaplastic thyroid carcinoma. Among the thyroid carcinomas, the incidence of medullary and anaplastic thyroid
carcinoma in low, but the rate of lymph node & distant metastasis from them are more common compared to other types. Follicular thyroid carcinoma has a low rate of lymph node metastasis as 10% and has a high occurrence of hematogenous metastasis
to
lung, bone, brain and liver. Papillary thyroid carcinoma accounts for 60~70% of whole thyroid carcinomas and the cervical lymph node metastasis is 21~81% including micrometastasis, but the distant metastsis is rare. In the case of bone
metastasis,
follicular type reveals most frequent, and the rate is about 5%, and more likely to be found on vertebra, pelvis, ribs, femur, and skull.
The clinical symptoms of bone metastasis are pain, swelling, patholgical fracture and radiologically osteolytic lesions can be observed. But distant metastasis of papillary thyroid carcinoma is very rare and especially, bone metastasis has hardly
been
reported.
The treatment modalities of metastatic thyroid carcinima to mandible are known as follows : thyroidectomy to treat primary site, resection of the affected site of mandible, external beam radiotherapy and radioiodine therapy etc.
