Lymphangiomas are benign lesions that are characterized by regional lymphatic dilatation, with no sex predilection. Approximately 50% to 60% of these lesions are evident at birth, and 80% to 90% are identified before the patient is 2 years old.1The head and neck are the most commonly affected sites, particularly the posterior triangle of the neck. Lymphangiomas may grow rapidly, infiltrating into muscles or around nerves and blood vessels, and produce considerable cosmetic and functional impairment, such as recurrent infections, respiratory distress, malocclusion, dysphagia, dysphonia, and dysarthria.
