Hemangiomas: update on classification, clinical presentation, and associated anomalies

Abstract

Infantile hemangiomas occur in 10% of children and are 3 times more common in female infants. The majority of hemangiomas are small, superficial tumors that require little, if any, treatment. During the last several years, new information regarding the classification, presentation, associations, and differential diagnosis of hemangioma has emerged and altered the management of these tumors. The purpose of this article is to briefly review some of these clinically relevant findings. A discussion of the pathogenesis and management of these potentially problematic tumors is beyond the scope of this article, but these topics have been addressed in several excellent reviews.
