2. What Are the Symptoms of Hemangiomas?

Sometimes a hemangioma is present at birth. More frequently, however, it does not appear on the infant’s body until he or she is a few months old. The main symptom of hemangiomas is rapid growth. The mark becomes a deep red, sponge-like mass. As it grows, the mass protrudes from the skin and may be unusual in shape.
