Primary tracheal schwannoma is rare.It is easy to be misdiagnosed as bronchitis,asthma due to the lack of special symptom.Diagnosis of schwannoma depends on a comprehensive examination.Surgery is the only effective mean.Here we reported a 17-year-old male,who suffered from cough for 10 months.A variety of tests confirmed that he had schwannoma.There is no significant change after tumor resection via rigid bronchoscope since two years ago.
