Imagine, you keep scratching the same spot on your arm, leg, or neck. It starts small at first, but the more you scratch, the more it gets worse. After a while, you notice that the skin in that spot has turned a little darker, thicker, and rougher, like a piece of leather. Sometimes, this scratching gets worse at night when you try to sleep. Have you had this experience? Then it is very important for you to be aware of this skin condition that we are talking about today called 'Lichen Simplex Chronicus'.
Simply put, what is Lichen Simplex Chronicus?
This is sometimes called 'Neurodermatitis'. Simply put, this is a condition where the skin in that area becomes thickened and rough due to constant scratching and scratching. It's like a cycle. First, the skin starts to itch for some reason. You scratch it. As you scratch, the nerves in that area become more stimulated, and the itching increases. So you scratch again. We call this the "itch-scratch cycle" . It's when this cycle continues that the skin begins to change.
This is actually considered a type of eczema. It is said that about 1 in 8 people in the world may have this condition. Although it can occur anywhere on the body, it is most often seen in areas that are easily touched, such as the hands, legs, and neck. This constant itching can sometimes cause things like stress and anxiety. At such times, the symptoms may feel worse.
What are the main symptoms of this condition?
These symptoms may appear suddenly, subside after a few days, and then reappear. This itching is especially felt at night when you are resting and trying to sleep. Let's take a look at the main symptoms.
| Symptom | What does it look like? |
|---|---|
| An unbearable itch | This is the main symptom. It's more severe than a normal itch. Sometimes it can be so severe that it wakes you up from sleep. |
| Skin discoloration | The area where the rash is located may turn red, purple, gray, brown, or darker than your skin tone, with a border that is more visible than the surrounding skin. |
| Thick, rough skin | Because of the constant scratching, the skin in that area becomes thick, dry, and scaly. It feels like a piece of leather when touched. |
Where are these characteristics most commonly seen?
Although this condition can occur anywhere on the body, it is most commonly seen in these areas:
- Arm, hand, shoulder, wrist, or elbow
- Neck, face, skull, lips, or cheeks
- Genital areas (scrotum, labia, or around the anus)
- Legs and ankles
Why is this happening to us? What are the reasons for this?
Doctors don't know exactly what causes it. But they think it's because the nerves in our skin are overly sensitive. That means that even something that's not usually a big deal to us can be a big stimulus to these nerves. There are certain triggers that can start this itch-scratch cycle.
| Triggers for itching | For example... |
|---|---|
| Allergic reactions | Skin allergies to certain soaps, creams, pesticides, or plants. |
| Insect bites | After being bitten by an animal like a mosquito or an ant, the person starts scratching the area continuously. |
| Dry skin | Skin can become dry and itchy, especially in cold weather or when you are constantly in air-conditioned rooms. |
| Stress and anxiety | Although many people don't know it, increased stress can increase skin itchiness. This is a connection between the mind and body. |
| Heat and sweating | Some people experience itching due to the saltiness of their skin when they sweat. |
| Minor skin injuries | After something like a skin break or cut occurs, you may start scratching the area. |
| Wearing tight clothes | When you wear tight clothing like denim pants all day, the skin in that area can get irritated due to constant rubbing. |
Who is most at risk of developing this condition?
It can develop at any age, but it is most common in adults between the ages of 30 and 50. It is also more common in women than men.
If you have the following conditions, your risk of developing this disease is slightly higher:
- Mental conditions such as anxiety or obsessive-compulsive disorder (OCD).
- Kidney disease.
- Other skin conditions such as psoriasis or contact dermatitis.
- Severe stress.
What complications can occur if you continue to itch?
You may be thinking, "What's that itching?", but this constant itching can cause serious problems.
- Pain or inflammation .
- Scratching the skin can cause open wounds and bleeding .
- Bacteria can enter through wounds and cause skin infections (such as scabs and pus-filled blisters).
- Swelling of the skin.
- Itching disrupts sleep .
- Scars remain after wounds heal.
- If you scratch your scalp, hair will fall out in that area.
Very important: Very rarely, there is a small risk of developing a condition called Squamous Cell Carcinoma, a type of skin cancer, due to this long-term skin irritation. So if you notice a new spot or change on your skin, don't ignore it. Be sure to see your doctor and get it checked out.
How does a doctor diagnose this?
Your primary care physician or dermatologist can easily diagnose this condition. He or she will first examine the affected area of your skin and then ask you a few questions.
For example:
- How long has this itching been going on?
- Is the itching constant, or does it come and go?
- Did you treat this at home?
- Have you changed the soaps and lotions you use lately?
What tests can be done?
Sometimes, your doctor may recommend several tests to confirm the diagnosis or to rule out another skin condition.
- Patch test: A test to see if you are allergic to something.
- Culture test: If a skin infection is suspected, a small sample taken from the area is tested.
- Skin biopsy: A very small piece of skin is taken and examined under a microscope to definitively diagnose the disease.
What are the treatments for this?
Treatment may vary from person to person, but the main goal for everyone is to stop that "itch-scratch cycle" we talked about and give the skin a chance to heal.
| Treatment method | What happens to it? |
|---|---|
| Covering the affected area | Once it's covered with a bandage or clothing, the itchy rash stops. |
| Moisturizers | These help retain moisture in the skin, protect it from drying out, and keep it soft. |
| Doctor-recommended creams | These include creams that reduce swelling and itching, numb the skin, or control the skin's immune response. |
| Light therapy | A treatment using special light rays for those with severe symptoms. |
| Counseling | Since stress and anxiety can increase itching, talking to a mental health counselor can help. |
Medications recommended by the doctor
Depending on your condition, your doctor may recommend the following medications:
- Corticosteroids: These are most often given as creams or ointments. They reduce skin discoloration, swelling, itching, and pain. They also help soften thick, rough skin.
- Antihistamines: If itching is caused by allergies, these pills can control it.
- Antibiotics: If a bacterial infection has developed due to scratching the skin, these are given as creams or pills to treat it.
- Capsaicin creams: This cream, made from chili peppers, numbs the nerves in the skin, reducing pain and itching.
- Tacrolimus or Pimecrolimus cream: These help control swelling and itching by calming the skin's immune system when steroid creams don't work well.
What do you do if you get injured while scratching?
This is very important. If you scratch and injure your skin, do these things right away to avoid infection.
1. Clean the wound: Wash the wound with cold water. Use a mild soap and a clean cloth to wash it thoroughly. Then pat it dry with a clean towel.
2. Apply some petroleum jelly: Apply a small amount over the wound to prevent infection.
3. Cover the wound: Cover the wound with a clean bandage. Change it at least once a day, or if the bandage gets wet or dirty.
4. Pay attention to the wound: If the wound changes color, swells, becomes more painful, or pus appears, see your doctor immediately.
Things you can do at home to heal your skin quickly
While following the treatment your doctor gives you exactly, you can also do these things at home to speed up the healing of your skin.
- Avoid scratching: I know this is not as easy as it sounds, but try your best. If you must scratch, rub your skin with your fingertips instead of using your nails.
- Relieve itching: Apply an ice pack, apply an anti-itch cream prescribed by your doctor, apply a cloth soaked in cold water, or take a cold shower.
- Keep your body cool: Avoid overheating and sweating.
- Wear soft, loose clothing: Choose clothes made from skin-friendly fabrics like cotton.
- Keep the itching area covered: Covering it with a light cloth or bandage will make you less likely to remember to lick.
