Is an old illness coming back from a wound on your skin? Let's talk about the Koebner Phenomenon

You may have a skin condition, such as psoriasis. Have you ever noticed that the same old condition suddenly appears again from a small wound or a cut on your skin? It's like the disease is starting from a new place. This is what we call the Koebner Phenomenon in medicine. This may be a bit new to some, so today we'll talk about it in a little more detail , but simply.

What is the Koebner Phenomenon?

Simply put, the Koebner Phenomenon is when a skin condition you already have, such as psoriasis or vitiligo, resurfaces in a new area of ​​your skin, such as an injury, cut, burn, or surgery. To be precise, a copy of the same old condition appears in a new area. Imagine, you have a small rash on your hand, you get a rash somewhere on your leg, and after a few days, the rash also appears in that same area. That's it.

This was first discovered and described in 1876 by a German physician named Heinrich Koebner. That is why this phenomenon is named after him. He also called it the 'isomorphic response'. The Greek word 'isomorphic' means 'equal shape'. This means that the new spots that form are similar in appearance to the original lesion.

How common is this?

This condition, called the Koebner Phenomenon, is most commonly seen in people with psoriasis. Some studies suggest that up to 25% of people with psoriasis may experience it. However, it is not limited to psoriasis.

This condition can also occur in people with warts, vitiligo, or a skin condition called lichen planus. However, it is not as common as lichen planus. In addition, Koebner's phenomenon has been reported to affect people with some other rare skin conditions.

What causes the Koebner phenomenon?

The exact cause of this is something that doctors still haven't found 100 percent, you know? It's still in the research stage. However, experts often think that it's caused by some kind of activity, perhaps overactivity, of our own immune system. That means they suspect that it may be related to autoimmune diseases.

For example, psoriasis, which we all know, is a disease that has an autoimmune connection. So, people with such diseases are more likely to experience this Koebner phenomenon. When there is a wound on the skin, certain signaling molecules and cells are activated during the healing process. Due to some abnormality in this process, the original skin disease may appear in a new place.

Who is at higher risk of developing this?

As we've discussed before, people with psoriasis are at the highest risk. In addition, there are several other skin conditions that can increase the risk of Koebner's phenomenon:

• Warts – These are caused by a viral infection.
• Vitiligo – A condition caused by the destruction of the cells that give skin its pigment.
• Lichen planus – This is also a condition that can cause inflammation of the skin, mouth, and nails.

Not everyone with these diseases will develop the Koebner phenomenon, but there is a risk.

What kind of skin lesions cause this?

The important thing here is that the Koebner phenomenon can be triggered by any injury that affects or damages both the top layer of the skin, the skin we see (the epidermis) , and the slightly deeper layer underneath (the dermis) . Think about things like this:

• Skin piercings such as injection sites, ear piercings, and nose piercings.
• When bitten by insects or other animals, for example, animals like mosquitoes and ants.
• When the skin is irritated. Let's just imagine that you are irritated by a stick while working in the yard, a cat is irritated, or a mosquito bites you and bites you badly.
• Some people intentionally break their skin (skin picking), things like that.
• Surgical wounds, other injuries, injuries from falls or cuts.
• When getting a tattoo, because that involves piercing the skin with a needle and injecting ink. This can also happen during tattoo removal procedures .
• Burns. It can be caused by fire, it can be caused by hot water. Sunburns can sometimes occur, but they don't cause the Koebner phenomenon as often as other injuries.
• Radiation therapy for diseases like cancer can also damage the skin, so this condition can sometimes occur from that area (this is also somewhat rare).

Simply put, it can start with any trauma to your skin.

What are the symptoms of the Koebner phenomenon?

The symptoms of Koebner's phenomenon vary depending on the underlying skin condition you have, and how severe (flare-up) that condition is at the time. New spots or skin changes usually begin to appear within 10 to 20 days of the injury . However, it can sometimes take weeks or, rarely, months for this to occur.

The main features that can be seen are:

• These new scars form on previously healthy, disease-free skin, in the same area where the injury occurred.
• They look exactly like your original skin disease.For example, if you have psoriasis, new patches will appear red like the psoriasis and will peel off in the same way as the psoriasis. If you have vitiligo, the new patches will also turn white.
• Most of the time, these are linear, as if the disease has spread along the wound. But this is not always the case, and can vary depending on the shape of the wound.

These spots sometimes appear as if someone has drawn a line with a ruler. That is also a special feature of this.

Can this cause complications?

This may sound a little scary to you. But to be honest, the Koebner Phenomenon usually doesn't cause any major complications. It's really just a flare-up of your old condition. That means that the new spots aren't life-threatening. However, sometimes the new spots can be as itchy and painful as the original spots. Also, in some conditions, like psoriasis, the spread of the condition can be a little disconcerting.

How to recognize the Koebner phenomenon?

There is no specific blood test or other test to diagnose this. When you see a dermatologist, he or she will examine your skin carefully. Then, they will ask about your past skin conditions, whether anyone in your family has had similar conditions, and whether you have recently had any injuries to your skin. All of this information, along with the appearance of the spots on your skin, will help the doctor determine whether this is Koebner phenomenon. Therefore , it is very important that you tell the doctor the truth and not hide anything.

How is this treated?

Here again, you may be surprised to learn that there is no specific treatment for the Koebner Phenomenon. The reason is that it is not a new disease, but simply a manifestation of your original skin condition. Therefore, it is treated in the same way as the original condition.

For example, if it is due to psoriasis, the same treatments for psoriasis, such as creams, ointments, pills, and sometimes phototherapy, will be used for these new areas. Similarly, if it is due to vitiligo, the same treatments will be used for that.

The most important thing is to follow your dermatologist's instructions exactly.

Can the Koebner phenomenon be prevented?

It can be difficult to completely prevent this, especially if you have a skin condition. However, there are things we can do to reduce the risk.

The best way is to control your primary skin disease well.That means, if you have psoriasis, you should follow your doctor's instructions to keep your symptoms as low as possible. The Koebner phenomenon is more likely to occur during the active phase of the disease.

In addition, you should minimize skin trauma and damage as much as possible.

These other things will also help:

• Reduce or stop picking at your skin, picking at your cuticles, and picking at your nails . It's okay to scratch, just don't scratch until it hurts.
• Protect your skin from the sun. When going out during the day, especially between 10 am and 4 pm, wear long-sleeved clothing if possible, a hat, and definitely use a sunscreen with a good SPF.
• Think twice about getting tattoos and some piercings. If you have these skin conditions, these can trigger the Koebner phenomenon.
• Use gloves when working with sharp objects or doing things like gardening.

What is the health status of someone with the Koebner phenomenon?

The health of someone with the Koebner Phenomenon is generally very good. As mentioned earlier, it rarely causes major complications. The best thing you can do is treat any new spots the same way you would treat your original skin condition.

It is also very important to follow your doctor's instructions exactly and take care not to injure your skin. If you manage your skin condition well in this way, the Koebner phenomenon will not have a major impact on your life.

When should I see a doctor?

If you have a skin condition that may be related to the Koebner phenomenon, and you notice any of the following, see your dermatologist or family doctor immediately:

• If your skin condition suddenly flares up, meaning the spots and redness increase.
• It's okay if the skin is itching unbearably or if it's in pain.
• If there is pus-like fluid draining from the wound, redness and swelling around the wound, or signs of infection such as fever , it is important to seek treatment immediately.
• If new skin blemishes appear, it is a good idea to inform your doctor about it.

What should I ask the doctor?

When you go to see your doctor, it's important to ask questions that are on your mind. This will help you understand your condition better. For example, you might ask questions like:

• "Doctor, what could be causing this Koebner phenomenon in me?"
• "How does this relate to the skin condition I currently have?"
• "What treatment method is best for me?"
• "How long will it take for these new spots to go away?"
• "What else can I do to prevent skin lesions and this Koebner phenomenon?"
• "What complications should I be concerned about?"
• "How long until I see the doctor again?"

In summary, things we need to remember

Okay, so here are the most important things you need to remember from what we've talked about. If you have a skin condition like psoriasis, vitiligo, or lichen planus, and you notice new spots that look like the same old lesions appearing where you had a cut, scratch, or burn on your skin, it's very likely the Koebner Phenomenon.

These new spots may appear a few days or even weeks after the injury. To properly diagnose this, you should see a dermatologist. He or she will prescribe the necessary treatment for you.

Keeping your underlying skin condition, such as psoriasis, under good control can reduce your risk of developing the Koebner phenomenon. However, sometimes these lesions can develop even when there are no symptoms. So it's important to protect your skin from cuts, burns, and other damage as much as possible. Take care of your skin. After all, healthy skin is the foundation for a healthy life.
