Lymphangiomas are uncommon congenital hamartomas of the lymphatic system, usually diagnosed in infancy and early childhood. Most lymphangiomas are present at birth (60%) and, by the age of 2 years, 80% to 90% are present. Tongue, palate, gingiva, lip, alveolar ridge and buccal mucosa are the most commonly affected sites in the oral cavity. Various methods have been tried for the treatment of lymphangioma, including surgery, radiation, laser therapy, sclerotherapy and radiofrequency ablation. This paper reports a case of lymphangioma in a 28 year-old female patient.
