Infantile hemangioma: an update.

Infantile hemangiomas (IH) are neoplastic proliferations of endothelial cells, characterized by a period of growth after birth, and eventual spontaneous involution. The course can be uneventful, culminating in spontaneous resolution; or it may be marked by complications such as bleeding; ulceration; infection; visual, feeding and breathing compromise; cosmetic and life-threatening complications such as congestive heart failure. Recognition of associated syndromes and impending complications of hemangiomas is of utmost importance. Great advances have taken place in the nomenclature, pathogenesis, immunohistochemistry, diagnostic workup and management of hemangiomas in the recent years. This article reviews current advances in the understanding of the pathogenesis, diagnostic tools, medical and surgical modalities of treatment for infantile hemangiomas.
