Anatomic distribution of cervicofacial lymphatic malformations based on lymph node groups

Lymphatic malformations (LM) are rare benign congenital malformations of lymphatic vessels [1]. The incidence of head and neck LM is approximately 1 of every 2000 to 4000 live births [2]. These lesions typically present as soft, colorless masses that generally grow proportionally with the child. Approximately 90% of lesions are diagnosed by five years of age and can be subject to rapid growth with infection or trauma [3]. Symptoms are commonly related to the size of the malformation and encasement of adjacent structures.
