title: Primary tracheal papilloma disguised as asthma: A case report.
abstract: BACKGROUND
  Tracheal papilloma presenting as asthma is a rare occurrence.
  
  
  METHODS
  We report a case of a 32-year-old male patient who presented with features of asthma. Flexible bronchoscopy demonstrated a large growth arising from the lower end of the trachea. Successful treatment using snare loop and argon plasma coagulation (APC) of the polyploidal growth was performed via flexible bronchoscope.
  
  
  RESULTS
  The patient had immediate relief of airway obstruction and histopathological examination of the neoplasm demonstrated features of papilloma.
  
  
  CONCLUSIONS
  Primary tracheal papilloma is mimicker of asthma, CT scan should be considered in patients with persistent chronic cough, or stridor. Endoscopic papillectomy is a safe and effective treatment and should be considered as first-line therapy for tracheal papilloma.
