Both lupus and psoriasis are autoimmune diseases that can affect the human skin. Although they share some of the same symptoms, they are distinct conditions. Psoriasis is more common than lupus. However, lupus can be more destructive because it involves more than the skin. Also, both conditions have different treatments and complications. Here’s everything you need to know about lupus and psoriasis, including the symptoms, the treatments, the causes, and more.

1. What is lupus?

Systemic lupus erythematosus or SLE is often referred to simply as lupus. It occurs when the immune system attacks the body’s tissues, leading to damage. The condition can affect many different parts of the body, including:

  • Skin
  • Joints
  • Kidneys
  • Lungs
  • Heart
  • Blood vessels
  • Brain

Lupus is a chronic, long-term disease which has no cure. But, some treatment options can help manage the symptoms.

2. What is psoriasis?

Like lupus, psoriasis is a chronic disease caused by an overactive immune system. But, it only affects the skin and causes red, scaly patches to appear on some parts of the body. The most common skin areas that can affected by psoriasis include:

  • Face
  • Skin folds
  • Scalp
  • Hands
  • Feet
  • Knees
  • Elbows
  • Nails
  • Genitals

People with psoriasis can have flares for the rest of their lives. But over time, the number and the severity of these flares will subside.

3. Similarities and differences between lupus and psoriasis

Because lupus and psoriasis are autoimmune diseases, they share some similarities. But, there are also some differences that you should look at. For example:


Experts still don’t know the exact causes of lupus and psoriasis. But, studies have shown that some factors can contribute to the conditions. These can include:

  • Genetic factors
  • Exposures to chemicals or solvents
  • Infections
  • Stress
  • The Western diet or the Standard American Diet

As opposed to lupus, psoriasis is a more common condition. It currently affects 125 million people in the world. Meanwhile, about 5 million people worldwide are suffering from lupus. In the United States, lupus affects 1.5 million people while psoriasis attacks up to 7.5 million people. 

Autoimmune effects

In both conditions, the body will produce antibodies. These can mistakenly attack the healthy cells. While psoriasis is limited to the skin, lupus causes damage to various parts of the body. Some of the main organs, such as lungs, kidneys and the joints are examples. Psoriasis can also affect the joints, which is called psoriatic arthritis.

Who’s most at risk?

People of any age can develop psoriasis, but those between 15 and 35 can be more at risk. Lupus mostly affects people between 15 and 44, especially pregnant women. Researchers have found that women of color are 2 to 3 times more likely to develop lupus than white women.

Lupus and psoriasis: Are the contagious?

Both conditions are not contagious. So, they can’t spread from one person to another.

Can they cause cancer?

Psoriasis and lupus can’t cause cancer. But, scientists find a link between psoriasis and some certain types of cancer. A cancer of the immune system, called Lymphoma, is a typical example.

4. Can you have lupus and psoriasis at the same time?

It’s possible for a person to have psoriasis and lupus at the same time. The symptoms can be especially apparent and uncomfortable. To know if you’re having the conditions, check your symptoms carefully.

Psoriasis symptoms

  • Thickened, pitted or ridged fingernails or toenails
  • Itching, burning, swelling or soreness in the affected area
  • Dry skin that itch, crack, or bleed
  • Small scaling and red spots
  • Skin patches covered with thick, silvery scales

Usually, the symptoms can be mild and disappear for some time. But during a flare, they can be very severe.
