title: Endoscopic CO2 laser surgery for an atypical carcinoid tumor of the epiglottis masquerading as a supraglottic cyst.
abstract: BACKGROUND
  Atypical carcinoid tumor is a neuroendocrine tumor; its occurrence in the larynx is uncommon, and clinical manifestations are rare. We report an unusual case of atypical carcinoid tumor of the epiglottis mimicking a supraglottic retention cyst.
  
  
  METHODS
  A 44-year-old woman complained of an intermittent globus sensation of the throat of 2 years' duration. A 1.0- x 0.8-cm cystic lesion was found over the tip of the epiglottis. A supraglottic retention cyst was initially diagnosed, and the patient was treated medically. Her symptoms persisted, so we performed a laryngoscopic biopsy, which suggested an atypical carcinoid tumor.
  
  
  RESULTS
  Transoral endoscopic CO2 laser surgery and bilateral elective neck dissection were subsequently performed. The 2-year follow-up did not reveal any locoregional recurrence or distant metastasis.
  
  
  CONCLUSIONS
  This aggressive neoplasm may cause only a few, unremarkable symptoms and masquerade as a supraglottic cyst. Endoscopic CO2 laser surgery can be used to resect this uncommon tumor, with oncologically sound results and without surgical morbidity.
