Large facial lymphatic malformation treatment using sclerosing agent followed by surgical resection: clinical and pathology report.

Lymphatic malformations are rare slow-flow vascular malformations, with high tendency to appear in the head and neck region. The treatment of these lesions ranges from follow-up to sclerosing agent injection to surgical excision. The authors present a case of a new born with large extensive lingual and submandibular lymphatic malformation, for which the patient underwent tracheostomy and gastrostomy insertion. He was then treated successfully with sclerosing agent injections followed by surgical excision, with 7 years follow-up. The second case presented is a two and a half baby with large lingual lymphatic malformation, treated successfully with doxycycline injections followed by intraoral excision of the lesion. Pathology of the excised lesion is then demonstrated, which shows for the first time the different layers affected by the sclerosing agent.
