Primary adenoid cystic carcinoma in the trachea (TACC) is a rare tumour. Tracheal bronchoscopy is always chosen as a routine approach to obtain a pathological diagnosis, but it can be associated with an increased risk of asphyxia.


We describe a case of TACC in a patient evaluated by chest computed tomography (CT) with three-dimensional reconstruction imaging and diagnosed by transoesophageal endoscopic ultrasonography. The pathological diagnosis confirmed tracheal adenoid cystic carcinoma.


We highlight the importance of CT and provide a successful exploration of transoesophageal biopsy as a safe alternative approach.

Keywords: Adenoid cystic carcinoma, Tracheal obstruction, Transoesophageal endoscopic ultrasonography, Three-dimensional computed tomography reconstruction, Case report

Core Tip: For large tracheal masses, tracheal bronchoscopy has certain limitations. This case highlights the importance of chest computed tomography for radiological assessment and provides a successful exploration of transoesophageal endoscopic ultrasound biopsy as a safe alternative biopsy approach.
