Erythrodermic Psoriasis

Articles On Types of Psoriasis

This is a rare but very dangerous form of psoriasis. It’s important to know the symptoms. If you think you have erythrodermic psoriasis, see your doctor right away.


Fiery red skin from head to toe is the main symptom. Your skin is also covered in scales and peels off in large pieces. It can be very painful and itchy. You might see tiny blisters called pustules that are filled with pus.

Symptoms can develop over time, but they can come on suddenly, too.

  • Joint pain
  • Rapid heartbeat
  • Swollen ankles

Why It’s Dangerous

Your skin is important to your overall health. It helps control your body temperature, keeps germs and toxins out, and holds moisture in. Erythrodermic psoriasis throws all this off, and the results can be life-threatening. They include a dangerously low body temperature (hypothermia), the loss of much- needed proteins and fluids, and severe illnesses like blood-infection' target='_blank' rel='noopener noreferrer' >sepsis and pneumonia. If you lose too much fluid, your heart won’t have enough blood to pump. That can lead to shock, kidney failure, and heart failure.


Psoriasis is an autoimmune disease. It's when your body’s natural defense system attacks healthy tissue. You’re more likely to get erythrodermic psoriasis if you already have plaque psoriasis, especially if it’s unstable. That means the raised, scaly patches don’t have well-defined edges. But it also affects people who’ve never had the disease.

It can appear if you suddenly stop taking your oral psoriasis medication. Other triggers include:

  • Alcoholism
  • Drug reaction
  • HIV
  • Infection
  • Oral steroid medicine
  • Severe sunburn
  • Stress


Your doctor will start by asking about your health history and doing a physical exam. They’ll ask if:

  • You have a family history of psoriasis
  • You’ve been exposed to a disease-related trigger like steroids, an infection, or an abrupt stop of psoriasis meds

Then they’ll check you for signs of psoriasis like:

  • Plaques
  • Joint pain
  • Psoriatic nail disease

They’ll probably do a skin biopsy. The doctor will remove a small piece of your skin and check it in the lab for signs of psoriasis.


If you have symptoms of erythrodermic psoriasis, don’t wait to get help. Go to the hospital immediately. Doctors will try to stop the flare-up as quickly as possible and protect you from complications.

  • Steroid cream or ointment moisturizers
  • Wet wraps
  • Oatmeal baths
  • Antibiotics to help prevent infection
  • Pain medication
  • Drugs to control itching
  • Medications to relieve anxiety

Can It Be Prevented?

Some risk factors can’t be avoided, like a family history of psoriasis. But you can:

  • Let your doctor know if you’re having a reaction to a new medication.
  • Be careful with anything that could irritate your skin.
  • Never abruptly stop taking a psoriasis medication.
  • Cover and treat wounds to prevent infection.
  • Use phototherapy devices carefully to avoid burns.
  • Manage stress.
  • Avoid alcohol.


Although most people with erythrodermic psoriasis do well when taking one or more treatment options, some people can’t be helped. The condition is fatal somewhere around 10% to 65% of the time. Most deaths are related to infections such as:

  • Pneumonia
  • Staphylococcal septicemia
