What kind of doctor treats Darier Disease?
A dermatologist, a doctor who treats skin conditions, usually treats Darier disease. A genetic counselor can also help affected people and their families. 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 is Darier disease?
Darier disease is a rare skin condition that runs in families. It is also called Darier-White disease or keratosis follicularis. It causes wart-like blemishes on the skin. The blemishes are usually yellowish and hard to the touch, and they can look greasy. Most people first notice them from late childhood to early adulthood.
Symptoms
Symptoms differ from person to person. They can include:
- Wart-like blemishes on the scalp, forehead, upper arms, chest, back, knees, elbows, and behind the ears.
- Greasy bumps that may grow bigger and form rough patches, sometimes with a brown or yellow crust.
- Itching that does not go away.
- Nail changes, such as red or white streaks that run up and down the nail, and V-shaped notches at the tip.
- Small pits in the palms of the hands and soles of the feet.
- Small bumps inside the mouth, most often on the roof of the mouth.
The blemishes can give off a strong odor. Most people have more blemishes in summer, when they are exposed to heat and humidity. Symptoms come and go. Some people have times with few blemishes, but the blemishes tend to come back. In some people, learning difficulties have also been reported.
Causes and who gets it
Darier disease is caused by changes, called variants or mutations, in a gene named ATP2A2. A gene is a set of instructions in your cells. This gene helps make a pump that helps control calcium inside cells. When the pump does not work well, skin cells do not stick together properly.
The condition is inherited in an autosomal dominant pattern. This means one changed copy of the gene is enough to cause it. An affected parent has a 50% chance of passing the gene change to a child in each pregnancy. Some people are the first in their family to have it. Males and females are affected equally.
Heat, sunlight, ultraviolet light, minor injury or friction, and some medicines can make blemishes worse. NORD estimates that 1 in 36,000 to 100,000 people have the condition. A form called the linear or segmental form affects only a band of skin and is generally not inherited.
How doctors diagnose it
Doctors diagnose Darier disease with a careful exam and a detailed history, including your family history. They look for the typical skin changes. They may also do a biopsy, which means removing a small piece of skin to look at under a microscope. A biopsy can show that skin cells are not sticking together.
Treatment
Treatment is aimed at the symptoms each person has. Sunscreen, loose clothing, moisturizing creams, and avoiding too much heat may make the disease less severe.
Topical retinoids are man-made forms of vitamin A that are put on the skin. They may reduce thick, scaly skin. They can irritate the skin. Keratolytics, such as salicylic acid, help soften and shed hard skin. Moisturizers and steroid creams are sometimes used for inflamed areas.
Retinoids taken by mouth are the medicines most often used for severe cases. They have side effects. Women must not become pregnant while taking a retinoid because these drugs could harm the baby. Pregnancy should also be avoided for some time after stopping the medicine. How long depends on which retinoid was prescribed. Retinoids should only be used under a doctor's supervision.
Antibiotics may be needed for a bacterial skin infection. Antiviral medicine has been used for herpes simplex infection of the skin. Reports suggest some newer medicines may help, but controlled studies are needed to confirm that. Genetic counseling is recommended for affected people and their families.
When to see a doctor
The skin can get bacterial, viral, or fungal infections that make Darier disease worse. Infected skin may smell bad, and the herpes simplex virus can cause pain. See a doctor soon if blemishes start to smell bad or become painful, since these can be signs of infection.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. Either can help with an evaluation, ongoing follow-up, and referral to a dermatologist or a genetic counselor.
Common questions
Is Darier disease inherited?
Yes, it can be passed down in families. One changed copy of the gene is enough to cause it, so a parent with the condition has a 50% chance of passing it on in each pregnancy. Some people have no family history, because the gene change can also happen new in a person.
Does Darier disease get worse in the summer?
Yes, it often does. Most people with Darier disease develop more blemishes in summer, when they are exposed to heat and humidity. Ultraviolet light can also increase the number of blemishes.
Do the blemishes come back after they improve?
Yes, they usually do. Some people have times when few blemishes are present, called remission. The blemishes tend to come back, called relapse.
Does Darier disease affect the nails?
Yes, most people with it have nail changes. Nails may be fragile, with splits along the length of the nail. They may also have red or white streaks that run up and down the nail, with V-shaped notching at the tip.
