Phacomatosis Pigmentovascularis: Causes, Symptoms, and Treatment
Medically reviewed by Harsha Moole, MD, Internal Medicine. Last reviewed: October 2, 2026.
What kind of doctor treats Phacomatosis Pigmentovascularis?
Care is often shared among specialists. A dermatologist usually manages the birthmarks, an ophthalmologist manages eye problems, and a vascular surgeon may help with blood vessel procedures. A primary care doctor often coordinates this team. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What it is
Phacomatosis pigmentovascularis is a very rare condition that a person is born with. It affects both the skin and the blood vessels close to the skin. "Pigmento" refers to areas of skin with extra pigment, and "vascular" refers to problems with blood vessels. People with this condition often have large birthmarks of two kinds: one flat and dark brown or gray blue, the other pink or red from widened blood vessels near the skin surface.
Symptoms
The most common signs appear at birth or soon after. Many people have a large flat blue gray birthmark called a mongolian spot and a pink or red birthmark called a port wine stain. In some cases, the condition also involves the eyes, brain, or other organs, which can lead to glaucoma or seizures. Many people only have skin findings and are otherwise healthy.
Causes and who gets it
Researchers believe this condition starts before birth, when cells that form skin color and blood vessels develop in an unusual way. It is very rare and does not usually run in families.
How doctors diagnose it
Doctors begin with a careful look at the skin and a health history. If organs other than the skin may be involved, they may order an eye exam, MRI scans, or sometimes a skin biopsy.
Treatment
There is no single treatment for the condition itself. Skin birthmarks may be treated with laser therapy, though results differ and several sessions may be needed. Glaucoma can be treated with drops, laser treatment, or surgery, and seizures can be managed with medicines.
When to see a doctor
A baby born with large or unusual birthmarks should be seen by a doctor. Call a doctor if new symptoms appear, such as eye pain, vision changes, seizures, or headaches.
How a direct primary care or concierge doctor fits in
A direct primary care doctor is paid a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. Either can be a steady home base for someone with a rare condition. When eye, brain, or blood vessel issues need expert care, they will refer the patient to the right specialist.
Common questions
Is phacomatosis pigmentovascularis contagious?
No. It is present from birth and cannot be passed to other people. It develops during growth before birth.
Will the birthmarks go away on their own?
The dark blue gray patches often fade slowly over years in some children. The pink or red birthmarks usually stay without treatment. Laser therapy can lighten them for many people, but results differ.
Can my child live a normal life with this condition?
Many people with this condition have only skin findings and stay healthy. When the eyes or brain are involved, treatment can help manage those problems. Each person's outlook is different, so regular medical follow up matters.
How common is this condition?
It is very rare. Only a few hundred cases have been reported in medical journals around the world.
