Ectopic thyroid tissue, 90% presenting in lingual zone, is often scanned by ultra-sonography or computed tomography. Most surgeons regard ectopic thyroid as metastatic foci from thyroid cancer, thus resection is recommended. Here, we reported a man with bilateral papillary thyroid cancer, accompany with normal ectopic thyroid tissue in right sternocleidomastoid muscle. In this case, we highlighted: (i) It is rarely reported that ectopic normal thyroid tissue presented in sternocleidomastoid muscle. (ii) The ectopic thyroid tissue may not always be metastatic foci even though bilateral thyroid tumors were confirmed to be papillary cancer. (iii) Contrary to radical excision of all ectopic thyroid tissue, we advocate that only patients who need to receive the radioactive iodine therapy after total thyroidectomy should remove the ectopic normal thyroid tissue.
异位甲状腺组织90%出现在舌部区域，常通过超声或计算机断层扫描进行检查。大多数外科医生将异位甲状腺视为甲状腺癌的转移灶，因此建议进行切除。在此，我们报告了一名患有双侧甲状腺乳头状癌的男性，其右侧胸锁乳突肌内伴有正常的异位甲状腺组织。在这个病例中，我们强调：（i）胸锁乳突肌内出现异位正常甲状腺组织的情况鲜有报道。（ii）即使双侧甲状腺肿瘤被确诊为乳头状癌，异位甲状腺组织也不一定总是转移灶。（iii）与彻底切除所有异位甲状腺组织相反，我们主张只有在全甲状腺切除术后需要接受放射性碘治疗的患者才应切除异位正常甲状腺组织。
