Hemangiomas of infancy are the most common benign tumors of childhood. They are composed of proliferating endothelial tumor cells and usually manifest as cutaneous birthmarks. In most cases, these tumors characteristically follow a natural course of regression. However, they can cause a tremendous amount of anxiety. Hemangiomas can threaten vital life processes if located in certain areas of the body. They may also be part of larger syndromes associated with high rates of life-changing morbidity and mortality. In all of these situations, hemangiomas are often referred due to the uncertainties that exist regarding the most efficacious diagnosis and management.
