Continual Cough: Experience and Lessons from a Case of Bronchial Adenoid Cystic Carcinoma

Background: Primary tracheal adenoid cystic carcinoma is a rare, slow-growing pulmonary malignancy. Due to the low incidence, clinicians are unable to diagnose and treat such disease, which is prone to cause misdiagnosis or missed diagnosis, consequently leading to delayed treatment. Case Presentation: Here, we reported a case of a 72-year-old woman who was diagnosed as primary bronchial adenoid cystic carcinoma after three years. At the time of the final diagnosis, lesion involvement was seen in the entire bronchus, and radical treatment was not available. Conclusions: Endoscopic bronchoscopy and palliative radiotherapy can relieve the symptoms of the patient and make the patient survive with the tumor for a long time.
