Update on hemangiomas of infancy

Purpose of review Recent clinical and basic science research has led to advances in the understanding of hemangiomas of infancy. Recent findings New developments include (1) the establishment of a relation between hemangiomas of infancy and placental tissue, (2) the discovery of unique immunohistochemical markers for hemangiomas of infancy, (3) the importance of morphology and location in determining potential risk for underlying complications, and (4) the discovery of becaplermin 1% gel as an effective therapy for refractory ulceration. Summary The morphology and location of a hemangioma of infancy are critically important factors in determining potential risk for complications. Ongoing research is bringing closer an understanding of the cause of hemangioma, which will provide opportunities for the development of interventional, and ultimately preventative, therapies.
