title: Case report: Cystic lymphangioma of the vallecula.
abstract: The incidence of vallecular cysts is low. They deserve full awareness of their existence because clinically they may produce upper airway obstruction. The case of a 20 month old infant in whom the large vallecular cyst was incidentally found on a routine examination is presented with a review of the literature.
