Psoriasis on the elbows presents as raised, inflamed, scaly patches of skin with defined edges. Eczema on the elbows typically causes less defined patches of dry, bumpy, rash-like skin, more commonly on the inner creases.

This article discusses the differences and similarities between psoriasis and eczema on the elbows in terms of symptoms, causes, diagnosis, and treatment. It also answers some frequently asked questions (FAQs) about the conditions.

Psoriasis and eczema on the elbows are two very different conditions; however, they share several similarities. Both conditions involve the immune system, have triggers that can cause symptoms to flare, and neither is contagious.

Psoriasis

Psoriasis is an immune-mediated disease that causes inflammation in the body and speeds up the production of skin cells. The skin cells build up and manifest as raised, inflamed, scaly patches of skin that typically have defined edges and can be mildly itchy.

Psoriasis affects over 7.5 million adults over age 20 in the United States (U.S.). However, it’s important to note that psoriasis can occur at any age, but symptoms can typically present between ages 15–25.

Eczema

Eczema is an inflammatory skin condition that presents as dry, itchy skin rashes and blisters. It can lead to skin infections. There are several different types of eczema, and each type has an individual set of symptoms.

Eczema affects more than 31 million people in the U.S. It can affect anyone at any age, including newborns as early as a few weeks following birth.

Psoriasis and eczema on the elbows can both be dry and itchy. Although, typically a person with psoriasis on the elbows will experience more intense itching than a person with eczema on the elbows.

Psoriasis

Symptoms of psoriasis on the elbows can include:

  • patches of thick, raised skin with defined edges called plaques
  • silvery, white, or red scaly patches
  • dry, itchy skin
  • a burning sensation
  • inflammation
  • soreness
  • cracking and bleeding

In people with lighter skin tones, psoriasis tends to appear red or pink with silvery-white scales. In people with darker skin tones, it is more likely to appear salmon-colored or violet with gray scales. Psoriasis can appear dark brown, making it difficult to see.

When psoriasis clears on darker skin, a person may see lighter or darker patches of skin where psoriasis once was.

Eczema

Eczema symptoms on the elbows can include:

  • dry, itchy, sensitive, scaly skin
  • patches of thick, rough, and hardened skin
  • possible weeping resulting in oozing or crusting
  • inflammation and swelling

Eczema can appear red on lighter skin, while eczema on the skin of color may appear ashen, gray, darker brown, or purple.
