Hemangiomas
I.
Definition:
 30%
of all hemangiomas are visible at birth. The remaining 70% become visible
within 1-4 weeks after birth. Hemangiomas occur 5 times more often in
females than in males and occur predominantly in Caucasians. Low
birthweight infants (less than 2.2 pounds) have a 26% chance of developing a
hemangioma.
83% occur on the head and neck area. The remaining 17% appear throughout the
the rest of the body (both externally and internally). In the early stages, some
appear either as bluish or reddish spots or flat patches. Rarely is a hemangioma
fully grown at birth.
