Ectopic thyroid tissue is a developmental disorder and is extraordinarily rare to occur in the central airway. To our knowledge, nearly few reports of primary ectopic thyroid carcinoma in the central airway with a normal eutopic thyroid gland have been published to date. This is the second case about malignant central airway obstruction caused by primary ectopic thyroid carcinoma.
65-year-old male was admitted to hospital for coughing accompanied by wheezing that recent exacerbated at night.The chest computed tomography scan revealed a soft tissue-density mass within the central trachea.The mass was removed and pathological analysis showed that it was ectopic thyroid carcinoma surprisingly. The goitrous thyroid gland was found in its expected location.
Ectopic thyroid carcinoma should be considered in the differential diagnosis of a pathological mass located in central airway.
异位甲状腺组织是一种发育障碍，在中央气道中极为罕见。据我们所知，目前几乎没有关于正常甲状腺中央气道内原发性异位甲状腺癌的报道。这是第二例由原发性异位甲状腺癌引起的恶性中央气道阻塞的病例。
一名 65 岁男性因夜间咳嗽伴喘息加重而入院。胸部 CT 扫描显示中央气管内有软组织密度肿块。肿块被切除，病理分析显示令人惊讶的是异位甲状腺癌。在其预期位置发现了甲状腺肿。
位于中央气道的病理性肿块，应考虑异位甲状腺癌的鉴别诊断。
