BACKGROUND
Dissemination of tumor cells from needle biopsy has been observed in a wide range of tumor types. Fine needle aspiration (FNA) biopsy has become accepted as the first-line test in the evaluation of thyroid nodules. Local recurrence of thyroid cancer from needle track seeding is an extremely rare complication of thyroid FNA.
CASE
A 59-year-old woman developed local recurrence of papillary thyroid carcinoma three years after FNA of the primary cancer. Local metastases developed in the skin and sternocleidomastoid muscle. The location of the recurrent cancer and the linear relationship of the metastases indicated that local recurrence was due to needle track seeding at the time of FNA.
CONCLUSION
Needle track seeding has been recognized as a possible, albeit rare, complication of FNA of thyroid cancer. Although proper FNA technique can reduce the potential for needle track seeding, its occurrence is an unavoidable complication of FNA evaluation of thyroid malignancies.
背景
在多种肿瘤类型中均观察到针吸活检导致肿瘤细胞播散。细针穿刺抽吸（FNA）活检已被公认为甲状腺结节评估的一线检查方法。针道种植导致甲状腺癌局部复发是甲状腺FNA极其罕见的并发症。
病例
一名59岁女性在原发性甲状腺癌FNA三年后发生乳头状甲状腺癌局部复发。皮肤和胸锁乳突肌出现局部转移。复发性癌症的位置以及转移灶的线性关系表明，局部复发是由于FNA时针道种植所致。
结论
针道种植已被认为是甲状腺癌FNA一种可能出现的并发症，尽管很罕见。虽然正确的FNA技术可降低针道种植的可能性，但其发生是甲状腺恶性肿瘤FNA评估中不可避免的并发症。
