Lymphangiomas are uncommon congenital hamartomas of the lymphatic system, usually diagnosed in infancy and early childhood. They are commonly located in the head and neck region, with the tongue being the most common intraoral site. The recurrence rate for lymphangiomas of the tongue is extremely high, and they can cause complications such as hemorrhage and obstruction of the upper respiratory airways. We report a case of a 17-year-old male patient with a lymphangioma of the tongue. The histopathology and treatment options are discussed, and the literature is reviewed.
