Cutaneous vascular lesions.

Vascular anomalies are lesions seen in all surgical disciplines, particularly in pediatric patients. Specialization in vascular anomalies involves a team effort, with the team consisting of plastic surgeons, general surgeons, neurosurgeons, pediatricians, interventional radiologists, dermatologists, ophthalmologists, otolaryngologists, hematologists, and pathologists. Inconsistent nomenclature in the literature has historically resulted in confusion about classification, diagnosis, and treatment. A biologic classification system has emerged, based on clinical observations, natural history, and cellular features, which separates vascular anomalies into two broad categories: vascular tumors and vascular malformations. For many vascular anomalies, photodocumentation, psychosocial support, and communication are important throughout the treatment course.
