Vallecular cyst: a cause of failure to thrive in an infant.

Congenital vallecular cyst is fairly uncommon in neonates and infants. Although benign in nature, it may cause stridor and even life-threatening airway obstruction in early infancy. A 3-month-old male baby presented with failure to thrive and respiratory distress was found to have a vallecular cyst. Marsupialization with CO(2) laser was performed.
