Management of infantile hemangiomas includes a combination of observation, medical therapy, laser treatments, and surgery. The nomenclature to describe these lesions has been standardized and should be adhered to. The goal of treatment is to obtain the best possible result commensurate with known developmental milestones. Current knowledge of the biology of these tumors as well as experience allows obtaining this goal. “Leave it alone, it will go away” is no longer universally acceptable advice for treatment of infantile hemangiomas.
