Abstract：
Papillary carcinoma of thyroid (PCT) commonly shows metastasis to central and lateral cervical compartment neck nodes. Submental nodes are rarely involved by PCT. Thus, its management is not clear. We report two young men who presented with submental nodal metastasis from PCT. Both underwent total thyroidectomy with central compartment neck dissection and modified radical neck dissection (MRND). Probable factors which might influence submental nodal metastasis are analyzed. We conclude that physicians should be aware of the possibility of submental nodal metastasis from PCT. A selective approach for neck dissection can be an alternative to MRND, reducing the morbidity in management of such cases.
摘要：
甲状腺乳头状癌（PCT）通常显示转移到中央和外侧颈淋巴结。PCT很少涉及下淋巴结。因此，它的管理不清楚。我们报告了两名年轻男子，他们因PCT而出现the下淋巴结转移。两者均接受了甲状腺全切除术，并进行了中央室颈清扫术和改良的根治性颈清扫术（MRND）。分析了可能影响下淋巴结转移的可能因素。我们得出的结论是，医生应该意识到PCT引起the下淋巴结转移的可能性。选择性颈淋巴结清扫术可以替代MRND，降低此类病例的发病率。
