Abstract: | Background: The aetiology and exact incidence of infantile haemangiomas (IHs) are unknown. Prior studies have noted immunohistochemical and biological characteristics shared by IHs and placental tissue.
Objectives: We investigated the possible association between placental anomalies and the development of IHs, as well as the demographic characteristics and other risk factors for IHs.
Patients and methods: Pregnant women (n = 578) were prospectively enrolled and their offspring followed for 9 months. Placental evaluations were performed and demographic data collected on all mother-infant pairs.
Results: We evaluated 594 infants: 34 haemangiomas [either IH or congenital (CH)] were identified in 29 infants, yielding an incidence of 4[middle dot]5% for IH (27 infants) and 0[middle dot]3% for CH (two infants). Placental anomalies were noted in almost 35% of haemangioma-related pregnancies, approximately twice the incidence noted in pregnancies with unaffected infants (P = 0[middle dot]025). Other risk factors for IH included prematurity (P = 0[middle dot]016) and low birth weight (P = 0[middle dot]028). All IHs were present by 3 months of age, and cessation of growth had occurred in all by 9 months of age. Most occurred on the trunk. Of note, 20% of identified IHs were abortive or telangiectatic in nature, small focal lesions that did not proliferate beyond 3 months of age. Only one IH required intervention.
Conclusions: This is the first prospective American study to document the incidence of IHs in infants followed from birth to early infancy. The association with placental anomalies was statistically significant. The overall incidence mirrors prior estimates, but the need for treatment was lower than previously reported.
What's already known about this topic?:
* Infantile haemangiomas (IHs), although often inconsequential, may cause significant disability or disfigurement.
* An association with aberrant placental or vascular stem cells has been hypothesized.
* The reported incidence varies widely, and complication rates as high as 20% have been documented.
What does this study add?:
* This is the first prospective U.S. study to document the incidence and demographics of IH in infants evaluated from birth.
* The incidence and risk of complications appear lower than previously reported.
* A statistically significant association with placental anomalies was identified.
