Maxillofacial lymphangioma

Lymphangioma is a benign tumor formed by malformations of lymphatic vessels. It is common in children and adolescents and occurs in the tongue, lips, cheeks and neck. According to its clinical manifestations and tissue structure, it can be divided into capillary type, sponge type and There are three types of cystic types. The capillary type is formed by the expansion of lymphatic vessels, and the expanded lymphatic vessels contain lymph fluid. The spongy lymphatic vessels are more severely dilated into multiple cystic cavities; the cystic lymphangiomas are more severely dilated. Lymphatic vessels are formed, which expand to form a large multilocular cystic cavity, which is filled with lymph fluid, so this type is also called cystic hydromas.
