PHACE syndrome

PHACE syndrome, also known as cutaneous haemangioma–vascular complex syndrome or Pascual-Castroviejo type II syndrome, is a phakomatosis that comprises of:

When sternal clefting and/or supraumbilical raphe are also present it is termed PHACES syndrome.

Clinical presentation

Clinical diagnosis of PHACE syndrome requires the presence of a characteristic segmental haemangioma or haemangioma >5 cm on the head (face or scalp) plus 1 major criterion or 2 minor criteria 5

Major criteria:

  • cerebrovascular: 
    • anomaly of major cerebral arteries
    • dysplasia of the large cerebral arteries
    • arterial stenosis or occlusion with or without moyamoya collaterals
    • absence or moderate-severe hypoplasia of the large cerebral arteries
    • aberrant origin or course of the large cerebral arteries
    • persistent trigeminal artery
    • saccular aneurysms of any cerebral arteries
  • brain: posterior fossa anomalies 
  • ocular: posterior segment anomalies
  • cardiovascular:
  • ventral or midline: sternal defects or supraumbilical raphe

Minor criteria:

Historic and etymology

Initially this syndrome was described as an association of large cutaneous haemangiomas of the head and anomalies of the cerebral vasculature by Pascual-Castroviejo in 1978 7,8. Subsequently, the name PHACE syndrome was coined by Ilona Frieden et al 2.
