Branchial cleft cysts are the most common lesions to arise laterally in the neck. Ectopic thyroid tissue within a branchial cleft cyst is rare, and a papillary carcinoma arising from this tissue is extremely rare. We present a case of a lateral neck cyst representing a primary papillary carcinoma that arose in ectopic thyroid tissue within a branchial cleft cyst in a 41-year-old woman. After the mass was surgically excised, thyroid ultrasonography, thyroid scintigraphy, and whole-body F18-fluorodeoxyglucose-positron emission tomography/computed tomography detected no abnormality. The negative findings notwithstanding, surgery on the thyroid gland was planned, but the patient refused it. Therefore, she was followed up with ultrasonography and scintigraphy for 5 years, during which time she exhibited no evidence of recurrence. Total thyroidectomy is still the primary option in such cases, but when it cannot be performed for any reason, vigilant follow-up is essential.
鳃裂囊肿是颈部外侧最常见的病变。鳃裂囊肿内的异位甲状腺组织很少见，而源自该组织的乳头状癌极为罕见。我们报告一例41岁女性患者，其颈部外侧囊肿为原发性乳头状癌，起源于鳃裂囊肿内的异位甲状腺组织。肿物手术切除后，甲状腺超声、甲状腺闪烁扫描及全身F18-氟脱氧葡萄糖-正电子发射断层扫描/计算机断层扫描均未发现异常。尽管检查结果为阴性，但仍计划对甲状腺进行手术，但患者拒绝。因此，对她进行了5年的超声和闪烁扫描随访，在此期间未发现复发迹象。在这种情况下，全甲状腺切除术仍是主要选择，但如果因任何原因无法进行，密切随访至关重要。
