Answer

Infantile hemangiomas occur in approximately 3% and 10% of white infants at birth and at age 1 year, respectively. [3, 4] Female, white, non-Hispanic newborns are more likely to be diagnosed with infantile hemangiomas. The incidence has increased in this cohort over the past several decades, likely reflecting the greater increase in prematurity in this population over the same period. [31, 32] The incidence of infantile hemangiomas is approximately 22-30% of preterm infants with birthweight less than 1 kg; for preterm infants with birthweight greater than 1.5 kg, [33] the incidence is the same as for term infants. An increased incidence is recognized in infants from multiple gestations.

The incidence is increased with older maternal age, maternal placenta previa, and preeclampsia. [34] Some, but not all, surveys have demonstrated increased incidence in infants born to mothers who have undergone prenatal chorionic villus sampling.
