Are you having annoying pimples and bumps on the back of your neck? Let's talk about Acne Keloidalis Nuchae (AKN)!

Have you ever noticed that some people have small blisters, or sometimes large bumps, on the back of their necks, where their hair starts? Sometimes they itch, hurt, and sometimes they even ooze. This is actually a skin condition. Today we are going to talk about this condition, which in medical terms is called Acne Keloidalis Nuchae , or AKN for short. Don't worry, let's understand this simply.

What exactly is Acne Keloidalis Nucae (AKN)?

Simply put, acne keloidalis nucca (AKN) is an infection or inflammation of your hair follicles . To be precise, it is a type of condition called folliculitis. It is a chronic condition , meaning it doesn't just go away. It mainly affects the skin on the back of your neck and scalp, where your hair grows.

This condition can cause various skin problems in that area. Over time , scars may form and hair may fall out in that area . Some people also call this `Folliculitis Keloidalis`. But let's remember the name AKN.

Who is most likely to develop this condition?

One might think that anyone can develop it. That's true, but AKN is most common in men, especially those with curly, wavy hair. It usually starts after puberty, which is when you're young.

Now you might be wondering why people with curly hair are more likely to develop ingrown hairs. One reason could be that curly hair is more likely to grow into the skin (ingrown hairs). Then the root of the hair can easily become infected.

Why does acne keloidalis nucca (AKN) develop? What are the causes?

Scientists still don't know exactly what causes AKN, but they do believe there are a few things:

• Skin damage: Sometimes the clothes we wear, for example , a shirt with a tight collar , or a helmet strap that is too tight, can cause the skin on the back of the neck to become damaged or torn. It is also thought that some hair cutting methods, especially very close shaves, can cause this condition.
• Changes in the immune system of hair follicle cells: The cells that fight disease in our body can sometimes start acting against the hair follicle.
• Hormonal effects: There is a theory that increased levels of certain male hormones (androgen hormones) or increased sensitivity of skin cells to those hormones may also be responsible.

But these are the presumed reasons. The exact reason is still under research.

How does this start? What are the early signs?

AKN usually starts as small, red, itchy papules on the back of the neck. Sometimes it can also appear as red patches on the skin. These blisters are itchy, so we often scratch them with our hands. Then they can become injured and easily infected. When infected, these blisters develop into pus-filled cysts (pustules) , similar to acne.

Imagine, a few days after you cut your hair, you develop two or three small blisters on the back of your neck, and you start to itch a little. Even if you don't pay much attention to it, if after a few days the blisters get bigger, hurt, and sometimes ooze a little pus, it could be the beginning of AKN.

How do symptoms change over time?

AKN is a condition that can get progressively worse. Over time, the skin begins to thicken, harden, and scar tissue (fibrosis, hypertrophic scars) forms where the original small blisters were. Sometimes these scars can turn into large, hard lumps (keloids) . These lumps can be as hard as rubber balls, and sometimes they coalesce to form a large scar.

Other symptoms that may be seen include:

• A crusty feeling on the skin.
• Constant itching .
• Pain , sometimes the lumps hurt when touched.
• Skin plaques (thickening of the skin, becoming crusty).
• Ingrown hairs, hair follicles becoming completely ingrown and turning into scars .
• Tufts of hair loss in that area.

This inflammation can sometimes wax and wane. It can subside for a few days and then come back again.

How do doctors diagnose this?

There is no perfect test to diagnose AKN. A doctor will usually diagnose it by examining your neck and the back of your head (physical exam). In addition, the doctor will ask you the following questions:

• What are your symptoms ?
• When did these start?
• Have these characteristics changed over time?
• Does your skin feel like it's getting worse because of something? (e.g. certain clothes, the way you cut your hair)
• Have you received any treatment so far?

Sometimes, if it is difficult to tell exactly what is going on based on the symptoms, the doctor may order a skin biopsy . This involves taking a small piece of skin from the affected area and examining the cells under a microscope. This helps confirm the diagnosis and choose the right treatment.

If you suspect an infection, such as pus coming out of the blisters, your doctor may send a sample of the pus for a ``culture`` test. This can help determine what type of germ is causing the infection. This can then make it easier to give the right treatment.

What are the treatments for this? Can it be completely cured?

Unfortunately, there is no cure for AKN, so the main goals of treatment are to control symptoms, prevent infections, and slow the progression of the disease.

The most commonly prescribed medications are:

• Topical or oral antibiotics to treat or prevent bacterial infections .
• Retinoids are medications made from vitamin A and help reduce symptoms.
• Steroids help reduce inflammation. These can be applied as a cream, taken as a pill, or given as an injection.

These treatments can control symptoms to a great extent, but it is very important to take the treatment exactly as directed by your doctor.

Are there other treatments?

If the AKN condition has become very severe and large lumps (keloids) have formed, the doctor may suggest other treatments.

• Surgical excision can be performed to remove damaged skin and skin grafting can be done to replace the damaged skin .
• Researchers are exploring other treatments, including laser therapy, phototherapy, and laser hair removal . However, treatments such as radiotherapy are only used in very severe cases when all other treatments have failed.

These treatments are not the same for everyone. Your doctor will decide what treatment is best for your condition.

Are there ways to prevent AKN from developing?

Since the exact cause of AKN is not known, there is no proven way to prevent it. However, it is believed that following certain steps can help reduce symptoms and, to some extent, prevent the development of new AKN.

• Reduce skin irritation: Protect the skin on the back of your neck from things like tight-fitting collars, tight hats, and tight helmet straps.
• Avoid cutting hair/beard close to the skin: When cutting your hair, tell the barber not to cut too short near the neck and close to the skin. It is better to cut with the clipper number slightly higher.

What is the outlook for someone living with this condition?

AKN is a chronic condition, meaning that it is difficult to expect a complete cure. So it can be a lifelong condition. But don't worry! With proper treatment and the self-care methods we've discussed, you can control your symptoms, prevent infections, and keep the disease from getting worse. So don't panic and follow your doctor's advice.

How can I take care of myself? Things I can do at home

If you have AKN, there are some simple things you can do for yourself to reduce symptoms and prevent infections:

• Dilute apple cider vinegar or tea tree oil and apply it to your skin: These have antiseptic properties that help prevent infections. But don't apply it directly, as it can be harsh on your skin. Dilute it with one part vinegar or tea tree oil to three parts water. Test a small area first to see if you have any allergies.
• Avoid clothing, hats, and hairstyles that irritate the skin: As we mentioned earlier, avoid tight collars and tight clothing. When cutting your hair, don't cut it in a way that irritates the skin around your neck.
• Clean the skin with antimicrobial cleansers: Gently cleansing the area daily can reduce the risk of infection. However, avoid using harsh soaps, which can dry out the skin and increase the risk of scarring.
• Apply Aloe Vera juice to the skin: Aloe vera is a natural ingredient that cools and heals the skin. It can help reduce itching and inflammation.

The most important thing is not to scratch, press, or squeeze the blisters. Doing so can increase the infection and make the scars worse.

When should you seek medical advice?

If you have any skin problems that are bothering you or interfering with your daily life, see a doctor immediately. This is common to any skin condition, not just AKN.

People with AKN are more likely to develop skin infections, so it's important to seek medical advice if you have any of these symptoms:

• If you get a fever.
• If pus is draining from the affected area.
• If the swelling or pain gradually increases over several days.

Symptoms like these may indicate that an infection is becoming more serious, so it's important to seek treatment quickly.
