Metastatic tumours of the oral cavity are rare constituting approximately one percent of all oral malignancies. These tumors are clinically significant as their appearance may be the first indication of an undiscovered malignancy at a distant primary site or the first evidence of dissemination from a known primary tumor. Thyroid cancer metastasizing to the jaw bones is a rare occurrence and very few cases have been described in literature. We present an additional case which in fact masqueraded as a primary jaw tumor. Metastasis to jaw bones is generally associated with poor prognosis with a majority of the patients dying within 6 months of diagnosis. Thyroid cancers however seem to be an exception to this, resectable solitary jaw bone metastasis from differentiated thyroid cancers is associated with a much better prognosis and therefore should be considered for metastatectomy.
口腔转移性肿瘤较为罕见,约占所有口腔恶性肿瘤的1%。这些肿瘤具有临床意义,因为它们的出现可能是远处原发部位未被发现的恶性肿瘤的首个迹象,或者是已知原发肿瘤播散的首个证据。甲状腺癌转移至颌骨的情况罕见,文献中仅有少数病例报道。我们在此报告另外一例实际上伪装成原发性颌骨肿瘤的病例。颌骨转移通常预后较差,大多数患者在诊断后6个月内死亡。然而,甲状腺癌似乎是个例外,分化型甲状腺癌可切除的孤立性颌骨转移预后要好得多,因此应考虑进行转移灶切除术。
