Vascular malformations include capillary, venous, arteriovenous, lymphatic and combined malformations. These lesions represent errors in vascular morphogenesis. Both genders are equally affected. They differ from hemangiomas in that these lesions are usually present at birth, present throughout life, and are GLUT1 negative on histology. Because these lesions persist over the life of the patient, it is important to identify the type of lesion to help guide management.
