Abstract：
BACKGROUND: Fine-needle biopsy is an accurate and cost-efficient tool for the assessment of thyroid nodules. It includes two primary methods: Fine-needle capillary biopsy (FNCB) and fine-needle aspiration biopsy. Needle tract seeding (NTS) is a rare complication of thyroid fine-needle biopsy mainly caused by fine-needle aspiration biopsy rather than FNCB. Here, we present an extremely rare case of a papillary thyroid carcinoma (PTC) patient with FNCB-derived NTS.
METHODS: We report a 32-year-old woman with PTC who showed subcutaneous NTS 1 year after FNCB and thyroidectomy. NTS was diagnosed based on clinical manifestations, biochemistry indices, and imaging (computed tomography and ultrasound). Pathological identification of PTC metastases consistent with the puncture path is the gold standard for diagnosis. Surgical resection was the main method used to treat the disease. After surgery, thyroid function tests and ultrasound scans were performed every 3-6 mo. To date, no evidence of tumor recurrence has been observed.
CONCLUSIONS: FNCB is a safe procedure as NTS is rare, and can be easily removed surgically with no recurrence. Accordingly, NTS should not limit the usefulness of FNCB.

摘要：
背景：细针活检是评估甲状腺结节的准确且具有成本效益的工具。它包括两种主要方法：细针毛细管活检（FNCB）和细针抽吸活检。针道播种（NTS）是甲状腺细针活检的罕见并发症，主要由细针抽吸活检而不是FNCB引起。这里,我们介绍了一例极为罕见的甲状腺乳头状癌（PTC）患者的FNCB衍生的NTS。
方法：我们报告了一名32岁的PTC女性，在FNCB和甲状腺切除术后1年出现皮下NTS。根据临床表现诊断为NTS，生物化学指标,和成像（计算机断层扫描和超声）。与穿刺路径一致的PTC转移瘤的病理鉴定是诊断的金标准。手术切除是治疗该病的主要方法。手术后,每3~6个月进行甲状腺功能检查和超声扫描.迄今为止,没有观察到肿瘤复发的证据.
结论：FNCB是一种安全的手术，因为NTS很少见，并且可以很容易地通过手术切除而没有复发。因此，NTS不应限制FNCB的有用性。
