Papillary thyroid cancer (PTC) is the most frequent histological subtype of thyroid cancer. The lymph node metastasis is found in a high proportion of patients with PTC at the time of surgery. In contrast, tuberculous lymphadenitis remains a common cause of cervical lymphadenopathy in Asian countries.
We present a 60-year-old woman with coexistence of papillary thyroid carcinoma (PTC) and cervical tuberculous lymphadenitis and to show the usefulness of fine-needle aspiration biopsy (FNAB) and quantiferon testing to distinguish a lymph node metastasis of PTC from tuberculous lymphadenitis.
FNAB and quantiferon testing are useful tools to check if enlargement of cervical lymph node is due to tuberculous infection, and a surgical plan should be carefully determined to avoid unnecessary surgical complications and the spread of tuberculous infection.
The coexistence of cervical tuberculosis should be considered in the etiology of an enlarged lymph node for patients with PTC.
甲状腺乳头状癌（PTC）是甲状腺癌最常见的组织学亚型。在手术时，高比例的PTC患者存在淋巴结转移。相比之下，结核性淋巴结炎仍是亚洲国家颈部淋巴结肿大的常见原因。
我们报告一名60岁女性，同时患有甲状腺乳头状癌（PTC）和颈部结核性淋巴结炎，并展示了细针穿刺活检（FNAB）和结核菌素试验在区分PTC淋巴结转移与结核性淋巴结炎方面的作用。
FNAB和结核菌素试验是检查颈部淋巴结肿大是否由结核感染引起的有用工具，应谨慎确定手术方案，以避免不必要的手术并发症和结核感染的传播。
对于PTC患者，在肿大淋巴结的病因中应考虑并存颈部结核。
