Difference Between Psoriasis vs Eczema

Psoriasis vs eczema are two of the most common rashes that dermatologists see in practice.  In most cases, these two conditions can be easily distinguished, but sometimes even the best dermatologist in Omaha can be challenged.

Difference Between Psoriasis vs Eczema

Even though treatments can be very similar for mild cases of psoriasis and eczema, establishing a solid diagnosis and telling these two conditions apart can be very important when it comes to determining:

  • what the very best treatment is
  • the likelihood of the condition is to be chronic
  • to better know if any additional testing is needed

We want to give you some very simple things that you can look for to try to distinguish and tell if you have either psoriasis vs eczema.

Psoriasis vs Eczema Location

First, the location of the rash can be very important.  Nearly any area of the body can be affected by both conditions, but psoriasis tends to favor certain specific areas most commonly.  These are usually pressure points, such as the

  • elbows
  • knees
  • buttocks
  • back of the scalp

The repetitive friction that tends to occur at these locations from our everyday activities can trigger psoriasis to develop in those areas in susceptible people.

Psoriasis

We tend to see that psoriasis typically is often bilateral and symmetric. By that we mean that if present in one area on one side of the body, it often is present in the same area on the other side of the body. Also, the appearance of the spot in the skin on one side of the body is often very similar to the appearance on the other side of the body. For example, if a person has a skin plaque of psoriasis of a certain size on their left elbow, they will often have very similar spot on the right elbow. This rule is not 100% but fits in many cases. In the case of eczema, we tend to see that this rule is often broken.

Psoriasis vs Eczema Spots

When looking closely at the spots of psoriasis and eczema, they usually look somewhat different.  The classic appearance of spots of psoriasis is red bumps and plaques that have overlying scaling, which often is a shiny or silvery scale.   In the case of eczema, we usually see red areas, but these may have overlying blisters or yellow crusting.

Symptoms

Symptoms can also be helpful to separate eczema and psoriasis.  Most patients with psoriasis have some symptoms with itching, but these are not very prominent. However, in the case of eczema itching tends to be much more severe. It may even make falling asleep and staying asleep more difficult.

A person’s family history and personal history can also be another useful tool to get a better idea about whether you are dealing with eczema or psoriasis.  Those of us with eczema may have a family history of eczema, asthma, or seasonal allergies. And of course, folks with psoriasis, may note a family history of psoriasis.   This factor, personal history/family history, is probably the least important factor when arriving at a diagnosis of eczema vs psoriasis. However, it still can be helpful.

Psoriasis and Eczema Treatment Options

As we noted, treatments for mild eczema and mild psoriasis can be very similar. For both conditions, regular usage of a moisturizer can help. Additionally, steroid cream including over-the-counter ones can also reduce the intensity of the spots. For over-the-counter remedies, hydrocortisone 1% ointment is best.

We hope this helps you to make a better determination about whether you have psoriasis or eczema.
