A 20-month-old African American girl presented with an enlarging mass in the anterior floor of the mouth that had been present since birth. No episodes of respiratory distress were noted. She had dysphagia with certain foods, but there was no failure to thrive. The patient's birth and medical history were unremarkable except for asthma.
Physical examination revealed a nontender 3-cm mass between the ventral surface of the anterior tongue and floor of the mouth that displaced the anterior tongue superiorly (Figure 1). The mucosal surface of the floor of the mouth and tongue appeared normal, without signs of inflammation. Lateral tongue movement was normal; however, anteroposterior and superoinferior movement was limited. There was no evidence of stridor, hoarseness, or symptoms of upper airway obstruction. The results of the rest of the head and neck examination were within normal limits.
