Abstract
BACKGROUND

Primary intratracheal schwannoma is an extremely rare type of benign airway tumor, especially in adolescents. The presenting symptoms are typically prolonged cough and wheezing that can be misdiagnosed as asthma in adolescent patients.

CASE

A 16-year-old adolescent girl admitted to a local hospital with symptoms of an irritating cough and wheezing was diagnosed with bronchial asthma and treated with budesonide and formoterol. Over the next year, the patient's wheezing and coughing symptoms gradually worsened and the antiasthma treatment was ineffective. One week prior to this admission, the patient developed dyspnea after catching a cold and was transferred to our hospital with a diagnosis of severe asthma. However, chest computed tomography and bronchoscopy showed a mass in the trachea. Primary intratracheal schwannoma was diagnosed by biopsy. Her symptoms were relieved by endoscopic resection by electrosurgical snaring combined with argon plasma coagulation. No relapse occurred during an 18 mo follow-up.

CONCLUSION

Primary intratracheal schwannoma should be considered in the differential diagnosis in adolescents with recurrent asthma-like attacks.

Core Tip: Primary intratracheal schwannoma is a rare benign airway tumor in adolescents. The presenting symptoms are typically prolonged cough and wheezing, and antiasthma treatment was ineffective in this patient. Chest computed tomography and bronchoscopy should be performed as soon as possible to clarify the diagnosis. Here we report a 16-year-old female patient with a primary intratracheal schwannoma misdiagnosed as severe asthma. This case report is intended to increase awareness for it and help avoid future misdiagnoses by physicians.
