Vascular malformations: Part I.
Cutaneous vascular malformations are rare disorders representing errors in vascular development. These lesions occur much less commonly but are often confused with the common infantile hemangioma. It is important to properly diagnose vascular malformations because of their distinct differences in morbidity, prognosis and treatment. Vascular malformations may be associated with underlying disease or systemic anomalies. Several of these syndromes are well defined and can often be distinguished on the basis of the flow characteristics of the associated vascular malformation.


OBJECTIVE
At the completion of this learning activity, participants should have a better understanding of the different types of cutaneous vascular malformations. Because of the importance of proper diagnosis of these lesions, participants should also be better able to direct correct management and treatment.
