Adenoid cystic carcinoma (ACC) is a malignant epithelial tumor that predominantly originates in the salivary glands of the head and neck. However, ACC arising in the thoracic cavity is a rare entity. Diagnosis of primary esophageal ACC (EACC) involves use of gastrointestinal endoscopic ultrasound fine-needle aspiration; however a low diagnostic yield has been reported in the literature. We describe an uncommon presentation of EACC debuting with predominant airway obstructive symptoms and diagnosed through endobronchial ultrasound-guided fine-needle aspiration. We propose the use of an endobronchial sonographic approach to diagnose EACC and other esophageal malignant neoplasms with mediastinal involvement and airway proximity.
腺样囊性癌（ACC）是一种主要起源于头颈部唾液腺的恶性上皮性肿瘤。然而，发生在胸腔的ACC是一种罕见的实体。原发性食管腺样囊性癌（EACC）的诊断涉及使用胃肠内镜超声细针穿刺；然而，文献报道其诊断率较低。我们描述了一例罕见的EACC表现，以主要的气道阻塞症状首发，并通过支气管内超声引导下细针穿刺确诊。我们建议使用支气管内超声检查方法来诊断EACC以及其他累及纵隔和靠近气道的食管恶性肿瘤。
