Surgical management of vascular tumors and malformations of the head and neck in adults.

Vascular tumors and malformations present a diagnostic and therapeutic challenge to many physicians. Because these lesions are rare, few surgeons have enough experience with them other than those practicing in tertiary vascular anomaly treatment centers. Some patients may have been misdiagnosed or mistreated during childhood and present in adult age with either recurrence or with an untreated lesion. Ideally, a multidisciplinary treatment team should be involved to discuss management with the patient including specialists in surgery, interventional radiology, pathology, hematology, genetics, and dermatology. As our understanding of the pathogenesis of these lesions grows, novel therapies are being employed which may decrease the need for surgery. Nevertheless, some lesions need definitive treatment with surgery. Improving understanding of the surgical management of vascular anomalies will improve cosmetic and functional outcomes for patients.
