Direct invasion of the trachea by an aggressive tumor originating in the thyroid gland is an unusual but well-documented phenomenon. The reverse situation, that is, a primary tracheal neoplasm invading by direct extension into the thyroid gland and presenting as a thyroid mass is apparently an even less common occurrence. A careful search of the literature has failed to reveal any recorded instances of this type of occurrence. We report a case of an adenoid cystic carcinoma arising in the trachea and invading the thyroid gland and recurrent laryngeal nerves causing vocal cord paralysis. The presentation of this lesion as a primary thyroid tumor is an unusual occurrence that serves to remind the clinician that in the differential diagnosis of thyroid masses one must include the possibilities of metastases or direct extension of a primary neoplasm from another organ.
起源于甲状腺的侵袭性肿瘤直接侵犯气管是一种不常见但有充分文献记载的现象。相反的情况，即原发性气管肿瘤通过直接蔓延侵犯甲状腺并表现为甲状腺肿块，显然更为罕见。仔细查阅文献未能发现任何关于此类病例的记录。我们报告一例起源于气管的腺样囊性癌，侵犯甲状腺和喉返神经导致声带麻痹。该病变表现为原发性甲状腺肿瘤是一种不寻常的情况，提醒临床医生在甲状腺肿块的鉴别诊断中必须考虑到来自其他器官的原发性肿瘤转移或直接蔓延的可能性。
