title: Use of intralesional formalin administration for treatment of a subepiglottic cyst in a horse.
abstract: METHODS
  A 4-year-old horse was evaluated for chronic coughing, mucopurulent nasal discharge, and failure to thrive.
  
  
  RESULTS
  Endoscopy was performed on the larynx, pharynx, and trachea and revealed an approximately 2-cm fluctuant subepiglottic cyst.
  
  
  RESULTS
  The subepiglottic cyst was treated with intralesional formalin administration. Following 2 injections, 2 weeks apart, the cyst was completely resolved with no evidence of scarring or epiglottic deformity.
  
  
  CONCLUSIONS
  Findings suggest that intralesional formalin administration for treatment of subepiglottic cysts may be a minimally invasive, economically suitable alternative to surgical treatments.
