Living with PHACE syndrome

A condition with a large birthmark (hemangioma) on the face or neck, along with brain, blood vessel, heart, or eye differences.

Understanding PHACE syndrome

PHACE syndrome is the association of a large hemangioma, usually on the face or neck, with one or more other birth differences.

PHACE stands for posterior fossa brain differences, hemangioma, arterial (blood vessel) differences in the head or neck, cardiac (heart) differences such as aortic coarctation, and eye differences. Symptoms and severity vary from person to person. Signs are seen during pregnancy, at birth, and in infancy.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Large hemangioma on the face or neck
  • Brain differences, such as Dandy-Walker malformation
  • Blood vessel differences in the head and neck
  • Heart differences
  • Small eyeball (microphthalmia)
  • Glaucoma or small optic nerve

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.
