Lymphangioma of the tongue.

Lymphangiomas are uncommon congenital tumors of the lymphatic system which usually occur in the head and neck; involvement of the tongue is rare. We report the case of a six-year-old Asian girl with a lymphangioma of the tongue. The differential diagnosis and treatment of tongue lymphangioma are also reviewed. It is important for emergency physicians to recognize unusual lesions such as lymphangioma, because early recognition and surgical excision of these tumors are essential for an optimal outcome.
