Tracheal adenoid cystic carcinoma is a rare malignancy. We report the case of a 65-year-old male who presented to our department due to a 3-month history of mild dysphagia without other associated symptoms. The neck, laryngeal, and hypopharyngeal examinations were normal. Ultrasound showed hypertrophy and marked hypoechogenicity of the left thyroid lobe without suspicious nodules. Fine needle aspiration of the hypoechogenic area revealed an adenoid cystic carcinoma. A tracheal origin was then suspected and it was confirmed by a flexible bronchoscopy that showed a tumor located in the proximal tracheal reducing its lumen by 50%. The biopsy confirmed the diagnosis of tracheal adenoid cystic carcinoma. We performed a computed tomography scan showing a mass at the angle between the trachea and esophagus infiltrating the left thyroid gland. Magnetic resonance imaging confirmed the tumor's important local and regionregional extension at the thyroid gland, esophagus, larynx, and mediastinum. The tumor was judged as unresectable and the patient received radiotherapy and an endotracheal sent. After a follow-up period of 2 years, the tumor remained stable, and the patient received This study aims to determine the clinical, radiological, and therapeutic aspects of advanced adenoid cystic carcinoma.
气管腺样囊性癌是一种罕见的恶性肿瘤。我们报告一例65岁男性患者，因3个月的轻度吞咽困难病史前来我院就诊，无其他相关症状。颈部、喉部和下咽检查均正常。超声显示左甲状腺叶肥大且回声明显减低，无可疑结节。对低回声区进行细针穿刺活检，结果显示为腺样囊性癌。随后怀疑肿瘤起源于气管，经柔性支气管镜检查证实，肿瘤位于气管近端，使管腔缩小50%。活检确诊为气管腺样囊性癌。我们进行了计算机断层扫描，显示气管与食管夹角处有一肿块，侵犯左侧甲状腺。磁共振成像证实肿瘤在甲状腺、食管、喉部和纵隔有重要的局部和区域扩展。该肿瘤被判定为不可切除，患者接受了放疗和气管支架置入。经过2年的随访，肿瘤保持稳定，患者接受了……本研究旨在确定晚期腺样囊性癌的临床、影像学和治疗方面的情况。
