What kind of doctor treats Exfoliative Dermatitis?
A dermatologist, a doctor who treats skin conditions, usually treats exfoliative dermatitis. Serious cases are treated in a hospital. 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 exfoliative dermatitis?
Exfoliative dermatitis is also called erythroderma. It means widespread redness of the skin. The skin also scales, peels, and flakes. It may itch, and hair loss can happen.
This can be serious. Erythroderma can quickly lead to serious complications, so doctors start treatment right away.
Symptoms
Symptoms may include:
- Redness over 80% to 90% of the body.
- Scaly skin patches and thickened skin.
- Skin that is itchy or painful, and may have an odor.
- Swelling of the arms or legs.
- A fast heartbeat.
- Loss of fluids, leading to dehydration, which means the body has too little water.
- Trouble keeping a normal body temperature.
The skin is often warm to the touch. Nails can become thick and brittle, and hair loss can occur. The skin may also get secondary infections, which are infections that start after the skin is already damaged.
Causes and who gets it
Several things can lead to exfoliative dermatitis:
- A reaction to some medicines or chemicals, such as phenytoin and allopurinol.
- A complication of other skin conditions, such as eczema and psoriasis.
- Some types of cancer, such as lymphoma, a cancer of the immune system.
Sometimes the cause is unknown. A skin condition that was already there is the most common cause in adults. Exfoliative dermatitis is more common in males.
How doctors diagnose it
Your provider will ask about your symptoms and health history. The provider also looks for triggers, such as infections, medicines, skin creams, and sun. The provider may check your skin with a dermatoscope, a tool that magnifies the skin. Most of the time, the cause can be found after the exam.
If needed, other tests may be ordered. These include a skin biopsy, which means a small piece of skin is checked under a microscope, and allergy testing. Lab results are often vague. They may not point to one cause.
Treatment
Treatment usually starts right away. It often involves strong steroid medicines to reduce inflammation, which is swelling and redness. Other treatments may include:
- Medicines to treat the underlying cause.
- Antibiotics for any infection.
- Dressings applied to the skin.
- Ultraviolet light.
- Fixing the balance of fluids and electrolytes, which are minerals in the body.
Skin care can include oatmeal baths and wet dressings, followed by bland moisturizers and mild steroid creams. Known triggers and irritants should be avoided. Treatment may not work well until the cause is treated.
In serious cases, the person needs to be treated in the hospital. The outlook depends on the cause.
When to see a doctor
Widespread red, scaly skin can be life threatening and often needs hospital care. Get medical care right away, even if you do not know the cause. Tell your doctor about every medicine you take, because some medicines can cause it. Do not stop a prescribed medicine on your own, because your doctor decides.
Contact your provider right away if your symptoms get worse or do not get better, even with treatment. Also contact your provider right away if you develop new lesions, which are new skin patches or sores.
Complications can include secondary infections that can lead to sepsis, dehydration, and heart failure. Sepsis is a bodywide response to infection.
Call 911 or go to the emergency room if you have trouble breathing, faint, or have a sudden change in mental state, such as confusion or being hard to wake.
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 look at your skin and your medicine list, follow up with you over time, and coordinate care with a dermatologist or hospital team.
