A hemangioma is a benign blood vessel tumor that appears within the first month of life. It may grow much faster than the child during its growth (proliferative) phase. Usually, the hemangioma reaches its maximum size when the child is between one and three years of age. 

After it reaches its maximum size, the hemangioma shrinks (involutes). Almost all hemangiomas shrink completely without treatment, leaving only some excess wrinkled skin we call fatty fibrous tissue that a plastic surgeon can easily remove. 

In some cases, hemangiomas cause medical problems that threaten the health or life of the baby. In this case, we may use steroids or chemotherapy to speed up the involution of the hemangiomas.
