Infantile hemangioma is the most common soft tissue tumor of childhood. Despite its frequency, it has only been in the last decade that these lesions have been better characterized and become the subject of significant clinical and translational research. Although most infantile hemangiomas are uncomplicated and do not require intervention, they can be a significant source of parental distress, cosmetic disfigurement, and morbidity. The wide spectrum of disease in the morphology of these lesions and in their behavior has made it difficult to predict the need for treatment and has made it challenging to establish a standardized approach to management.
