Background: Adenoid cystic carcinoma (ACC) refers to a salivary gland neoplasm. Tracheal adenoid cystic carcinoma that invades the tracheal prominence is a relatively rare tumor among thoracic diseases. Objective: To explore the epidemiology, diagnosis, treatment and future development of tracheal adenoid cystic carcinoma (TACC). Methods: With asymptomatic invasion of the tracheal prominence, a case of tracheal adenoid cystic carcinoma with asymptomatic invasion of the tracheal prominence was reported. The clinical management process and surgical methods were introduced, and related literature was reviewed and summarized. Results: The patient was admitted due to tracheal augmentation mass for half a month. Chest CT at admission displayed the soft tissue density shadow behind the tracheal augmentation process. After the completion of other examinations, tracheal tumor resection and tracheal reconstruction were performed. Postoperative routine pathology exhibited that it was TACC and without inguinal lymph node metastasis. Conclusion: TACC is a low-grade tracheal tumor with low incidence, delayed clinical manifestations and lack of specificity as well. CT and bronchoscopy are helpful for the diagnosis of suspected patients. Meanwhile, radical surgical resection is the first choice of treatment. Adjuvant therapy can improve the therapeutic effect. Targeted immunotherapy is the developing direction of treatment.
