Three types of lymphagniomas are distinguished in the literature: the cavernous lymphangioma, the lymphangioma simplex, and the cystic lymphangioma (1).
These lesions can be classified in to four categories: superficial cutaneous lymphangioma (composed of small, thin-walled lymphatics), cavernous lymphangioma (composed of dilated lymphatic vessels with surrounding adventitia), cystic lymphangioma (consisting of huge, macroscopic lymphatic spaces with surrounding fibrovascular tissues and smooth muscle), and diffuse systemic lymphangioma (in which lymphatic channels appear to be dissecting dense collagen bundles).
Cavernous lymphangioma are subcutaneous and commonly affect the oral cavity, neck, and tongue.
