title: Epithelial-myoepithelial carcinoma arising from the subglottis: a case report and review of the literature.
abstract: BACKGROUND
  Epithelial-myoepithelial carcinoma is an extremely rare disease that usually occurs in the parotid gland but can occur in a variety of sites such as the nasal cavity, paranasal sinus, and base of the tongue.
  
  
  METHODS
  We report a rare case of epithelial-myoepithelial carcinoma, which developed in the subglottic region. A 78-year-old Korean woman visited our hospital complaining of hoarseness, which had developed 1 month previously. Flexible laryngoscopy showed a round mass that blocked approximately 80 % of the tracheal diameter. Complete excision of the mass was carried out under general anesthesia, using a transoral approach. Epithelial-myoepithelial carcinoma was diagnosed following immunohistochemical analysis.
  
  
  CONCLUSIONS
  We report a rare case of epithelial-myoepithelial carcinoma that occurred in the subglottic region. To the best of our knowledge, only one other case has been reported since this disease was first identified approximately 40 years ago.
