Lymphangioma is a benign, hamartomatous tumor of the lymphatic channels. It is usually found in the head and neck region. Most lymphangiomas are present at birth and are usually diagnosed in infancy or early childhood. When lymphangioma occurs in the mouth, the anterior two thirds of the tongue is the most commonly affected region. A risk of secondary growth is classically described after surgical reduction. In this paper, we present 9 cases of tongue lymphangioma. We provide a literature review of tongue lymphangioma.
