PHACE syndrome is the association of a large hemangioma, usually on the face or neck, in combination with one or more other abnormalities. Every infant diagnosed with PHACE syndrome has different medical needs. Some have mild symptoms while others have more severe symptoms. PHACE syndrome is uncommon but may have been misdiagnosed in the past. It affects girls nine times more often than boys.
PHACE is an acronym that refers to a group of abnormal medical findings. When these occur together, doctors can diagnose PHACE syndrome.
- Posterior fossa – brain malformations that are present at birth
- Hemangioma – This usually covers a large area on the skin of the head or neck (greater than 5 cm). The term "segmental" is sometimes used to describe these hemangiomas.
- Arterial lesions – abnormalities of the blood vessels in the neck or head
- Cardiac abnormalities/aortic coarctation – abnormalities of the heart or the blood vessels that are attached to the heart
- Eye abnormalities

What causes PHACE syndrome?
There has been a lot of progress in recognizing and understanding PHACE syndrome, but there is no known cause. Researchers at Children's Wisconsin, the Medical College of Wisconsin and the Hemangioma Investigator Group have ongoing research studies. These groups recently have published criteria for diagnosis of PHACE syndrome so earlier detection may lead to earlier and safer treatments.
These are examples of hemangiomas that may be seen in infants with PHACE syndrome:
How is the diagnosis of PHACE syndrome made?
We recommend that any infant with a large facial hemangioma be evaluated by a pediatric dermatologist, a pediatric ophthalmologist or a physician who is familiar with PHACE syndrome. If PHACE syndrome is suspected, special radiology tests may be needed. These tests may include an MRI or MRA of the head, neck and chest and an echocardiogram. If the tests are abnormal, the infant should be seen by a team of specialists. The pediatric specialists who may be needed to treat these infants include a dermatologist, hematologist/oncologist, ophthalmologist, radiologist, neurologist, geneticist, cardiologist and otolaryngologist who are all familiar with treating this syndrome.
What are the complications of PHACE syndrome?
The hemangiomas found in patients with PHACE syndrome are more likely to have complications. If the hemangioma is near the eye it may cause problems with vision development in that eye. The facial hemangioma on these infants is more likely to break open and bleed. When a hemangioma breaks open, it usually is very painful, and the infant needs prompt attention and often, pain medication. Fussiness, poor feeding and difficulty sleeping are all signs that the infant may be in pain. More serious complications may develop depending on the other problems that are found in the infant.
Infants who have PHACE syndrome may be at risk for other neurological problems even after the hemangioma has gotten better. These problems may include migraine headaches, seizures, developmental delays, speech delays and very rarely ischemic strokes.
Infants with cardiovascular defects need close monitoring by a pediatric cardiologist for ongoing care and treatment. The most common cardiac defects associated with PHACE syndrome are coarctation of the aorta or other aortic arch abnormalities. If severe, the coarctation may require surgery.
Infants need to have frequent visits with an ophthalmologist if there are signs of eye involvement. They may need early treatment to prevent vision loss.
