Introduction:
Psoriasis vs Fungal Infection: How to tell the difference? – If you’ve ever seen a red, itchy area on your skin and thought “Is this a fungal infection or could it be psoriasis?” – you are not alone. These two conditions have very similar similarities to each other especially early in their course which can create confusion regarding diagnosis.
Fungal infections and psoriasis both have similar symptoms that cause itching, redness to the skin as well discomfort, but they have completely different causes; one relates to an overactive immune system while the other results from a fungal infection. Therefore, using the wrong treatment may potentially make your condition worse.
For this reason, it is important to know the difference between them so that you can receive the proper treatment and care.
What is Psoriasis?
Psoriasis is a chronic, non-contagious autoimmune disease. In this condition, the body’s immune system mistakenly attacks its own skin, failing to recognize it as “self.” Due to this wrong immune signal, skin cells multiply much faster than normal and accumulate on the surface. This leads to red, thick, scaly patches, itching, and sometimes pain or cracking of the skin.
Psoriasis is not an allergy or infection, it reflects an internal immune imbalance and needs long-term, holistic management.
What is a fungal infection?
On the other hand, fungus growing on your skin creates a fungal infection. Fungi prefer to grow in warm and wet parts of your body where there is a lot of sweat.
Some of the more common signs of a fungal infection include:
- Red, itchy rashes
- Round or circular patches with slightly raised edges
- Moist skin or peeling skin around the infected area
Unlike with psoriasis, when you have a fungal infection, it can spread to other parts of your body or to other people through contact or sharing items with others.
Why do people get confused?
Generally, both conditions (psoriasis and fungal infections) look similar at first glance (red, itchy and irritated skin), especially in the groin, under the arms or in skin folds where both conditions may be present (inverse psoriasis vs. fungal infection).
Because both conditions may be present, many individuals will find themselves using over-the-counter medications without fully understanding what they are treating (this can lead to other problems).
The following are the primary differences you’ll want to be aware of:
A. How it looks –
Psoriasis is characterized by thick, dry patches and usually has a whitish/silverish color (i.e., “Scaly” appearance). A Fungal Infection usually presents as a red patchy rash with the typical ring shape and clear center.
B. How it feels –
Psoriasis can be very itchy as well as painful/burns. A Fungal Infection can also be very itchy, but will feel more uncomfortable.
C. Where is it found –
Psoriasis is typically found on the elbows, knees, scalp, and lower back. A Fungal Infection can be found in the groin area, feet, and underarms.
D. Moisture/Dryness –
Psoriasis is typically dry and has scaling; while a Fungal Infection is generally wet/moist.
E. Spreading –
Psoriasis does not spread from one individual to another, whereas a Fungal Infection can spread via contact and humidity.
F. Treatment –
Treatment for Psoriasis requires both specialized treatments and lengthy continuation of such treatments. Treatment for a Fungal Infection may be improved with antifungal cream.
How can you tell when to suspect Psoriasis?
You may have a case of Psoriasis if:
- The condition recurs over and over again
- You notice thick, dry patches of skin
- It appears on your elbows, knees or scalp
- You have tried using non-prescription antifungal creams and had no success
When is it likely to be a Fungal Infection?
You may have a fungal infection based upon the following clues:
- The rash is expanding in size and/or the rash shape resembles a ring
- The rash is located where there is moisture (i.e. you sweat heavily) or perspiration occurs (i.e. in humid climate).
- The rash is very itchy
- Your rash has improved based upon use of some type of antifungal product
Why is it important to get the right diagnosis?
It is very important to get the right diagnosis.
If you apply antifungal medications to Psoriasis, then you may not get better. However, applying steroid versus antifungal creams can actually worsen the symptoms of fungal infection.
Therefore, if you are uncertain about your condition, you should contact a doctor instead of trying to figure it out on your own.
Basic habits that benefit everyone
Regardless of the condition, there are some basic habits that can always be helpful:
1. Keep your skin clean and dry.
2. Wear clothing that is loose-fitting and breathable.
3. Don’t scratch an area that is affected.
4. Use skin-friendly and gentle products.
5. Remember to maintain good hygiene, particularly in the summer season.
Conclusion:
Psoriasis and fungal infections may look alike, but their causes, cures, and behaviours differ greatly. Therefore, it is important to closely watch your symptoms (i.e., whether your skin is dry or wet, where on your body the symptoms are, and how well they respond to treatment).
If you have any concerns or changes that appear not to improve, it is important to seek help in order to ensure you obtain the correct diagnosis, which is key in order to obtain an effective treatment and sustained relief.
Your skin communicates with you, learning to recognize what it is telling you will help you tremendously.
Frequently Asked Questions (FAQs)
