Infantile Hemangioma: New Insights on Pathogenesis and Beta Blockers Mechanisms of Action
Abstract
Infantile hemangioma (IH) is a common, benign vascular tumor of infancy. The tumor displays a unique life cycle consisting of a proliferating phase, occurring in the first months of life, followed by an involution phase that lasts several years. Thus, IH represents a model of post-natal vasculogenesis/angiogenesis and vessel regression. In recent years, beta-blockers, have been shown to be effective treatment for IH and replaced the corticosteroids as first line treatment of complicated lesions. The mechanisms underlying their effect have not been fully elucidated. However, significant advances have been achieved. This review will focus on the pathogenesis of IH and on the mechanism of action of the beta-blockers treatments, including their effects on vascular tone, angiogenesis and vasculogenesis.
