What kind of doctor treats Graham Little Piccardi Lassueur Syndrome?
A dermatologist, a doctor who specializes in diseases of the skin, hair, and nails, usually treats this condition. Because it is rare, many general doctors refer patients to a dermatologist for diagnosis and treatment. 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
Graham Little Piccardi Lassueur syndrome is a rare skin condition and a type of lichen planus, which causes itchy, purple, flat bumps on the skin. It has three main features: scarring hair loss on the scalp, hair loss in the armpits and groin, and small spiny bumps around hair follicles on the body.
Symptoms
The most common signs are patchy scarring hair loss on the scalp and hair loss in the armpits and pubic area. Hair on the scalp does not grow back because the condition scars the hair follicles. Many people also develop itchy, flat, shiny, purple or reddish bumps on the arms, legs, or trunk. Nails may become thin, ridged, damaged, or lost.
Causes and who gets it
Doctors do not fully know what causes this syndrome. It is considered an autoimmune problem, meaning the body's defense system attacks its own healthy tissue by mistake. It is related to lichen planus. It has been reported more often in women, and it usually appears in adults.
How doctors diagnose it
A doctor will examine the skin, hair loss, and nails. The most helpful test is a skin biopsy, in which a small piece of skin is examined under a microscope. It can show changes pointing to lichen planus and follicle scarring. Because the condition is rare, a doctor may refer the patient to a specialist.
Treatment
There is no known cure. Treatment focuses on easing itching, calming inflammation, and slowing further damage. Doctors may prescribe corticosteroids, applied to the skin, taken as a pill, or injected. Hair lost in scarred areas usually does not grow back, but treatment often controls the itching and stops the condition from getting worse.
When to see a doctor
Anyone who notices patchy hair loss in the armpits or groin, along with itchy bumps or nail changes, should see a doctor. Early care may help before more scarring happens. Those already diagnosed should call if itching becomes hard to manage, new hair loss appears, or treatment causes side effects.
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 be a helpful first stop. When the pattern suggests this syndrome, they will refer the patient to a dermatologist, since a biopsy and specialist treatment are usually needed.
Common questions
Is Graham Little Piccardi Lassueur syndrome contagious?
No. It is not caused by an infection, so it cannot be passed to other people through touch or close contact.
Will the hair grow back?
Hair lost in scarred areas usually does not grow back, even with treatment. Treatment aims to relieve symptoms and protect the hair that remains.
Is this condition dangerous?
It is not usually dangerous to overall health. The main problems are itching, permanent hair loss in affected areas, and nail damage.
Can children get it?
It is rare in children. It most often appears in adults, and it has been reported more often in women.
