title: PHACE(S) syndrome.
abstract: PHACE(S) syndrome is a neurocutaneous disorder of unknown etiology. The acronym refers to the commonest features of PHACE: posterior fossa malformations, large facial hemangiomas, cerebral arterial anomalies, cardiovascular anomalies, and eye anomalies. When ventral developmental defects such as sternal clefting or supraumbilical raphe occur, the PHACES acronym may be used. The hallmark feature of PHACE is the presence of one or more large facial infantile hemangiomas that occupy at least one facial segment. Infantile hemangiomas differ from the capillary malformation (port wine stain) of Sturge-Weber syndrome, and the arteriovenous malformation of Wyburn-Mason syndrome, distinguishing PHACE syndrome from other neurocutaneous disorders with red birthmarks. The true incidence of PHACE has not yet been established. Girls are more commonly affected than boys. Cerebral vascular anomalies are probably the most common extracutaneous feature. Given that several organ systems are involved, a multidisciplinary approach to disease surveillance and treatment is advised.
