Many people suffer from either psoriasis or eczema, and these common skin conditions are often confused. While they share some symptoms, they’re different in important ways. To get the help you need for either problem, learn the 5 ways to tell the difference.
What do psoriasis and eczema have in common? “Both are red, scaling skin conditions, and clinically can look similar,” says David Crowe, MD, Chair of Dermatology at MetroHealth. Here are five differences:
1. They occur in different places
- Eczema tends to show up in the skin’s creases, like inside your elbows or behind your knees. Spots of eczema can also form on your face or neck. Some adult sufferers have patches on their hands and feet.
- Psoriasis is seen in the more exposed surfaces of the skin, rather than in the folds. It often forms over the knees or elbows. The belly button is another area, as well as the palms of your hands and soles of your feet.
2. They look similar, but have key differences
- Both conditions are red in color, but psoriasis tends to be more well-defined. While psoriasis is a deeper red than eczema, the scale pattern can appear to have a silver color.
- Patches of eczema are poorly defined and have different types of scale depending on the stage of disease.
3. They have different symptoms
- Eczema is associated with a significant degree of itching. Sometimes there is associated clear drainage.
- Patches of psoriasis do not have drainage, and sometimes there is no associated itch.
4. They are linked to different conditions
- Eczema often shows up alongside asthma and seasonal allergies. Kids with eczema are more likely to have other allergies, including pet or food allergies.
- Psoriasis is linked to a severe type of arthritis. If you have psoriasis with joint pain, that’s called psoriatic arthritis.
5. They both run in families, but one more than the other
- Eczema tends to have a stronger genetic link. Parents with eczema tend to have children with eczema.
- Psoriasis can also be inherited, but the genetic condition isn’t as strong. While children can get psoriasis, it’s more commonly seen in adults.
Seeking Care for Eczema and Psoriasis
For mild patches of either eczema or psoriasis, the first line of treatment is usually steroid cream. But for more severe or persistent cases, doctors prescribe other medicines.
That’s why it’s important to get the right diagnosis. Both conditions are related to the immune system, but in different ways. “We have treatments for different portions of the immune system for each condition,” Dr. Crowe says.
If you suspect you or your child has either psoriasis or eczema, start by seeing your primary care doctor. They may recommend you see a dermatologist. Referrals are not required. Call 216-778-DERM (3376) to schedule an appointment. For more information, visit metrohealth.org/dermatology.
