Do you have dark velvety patches on your skin? (Acanthosis Nigricans) Let's talk about this!

Have you ever noticed that some areas of your skin, especially on your neck, armpits, or groin, are darker than other areas, and have a velvety texture? Sometimes when we see this, we think that this is dirt, and that it will go away after a good shower, soap, and scrubbing. But in reality, this is nothing more than dirt. We medically call this condition Acanthosis Nigricans. Don't worry, although this name may be a little strange, it is very important for you to know about it.

So what is Acanthosis Nigricans? Where does it occur?

Simply put, it's a dark brown to black discoloration that appears on the skin. It's like a patch of skin that has changed color. As I said before, when we see it, we may think it's just a layer of dirt. But remember, it's not something that can be removed by bathing, soaping, and scrubbing.

These velvety, slightly thickened patches are usually found in areas where the skin folds on our bodies. For example:

• Around the neck, especially in the skin folds at the back of the neck
• Under the armpit
• In the Ikili area
• Under the breast (in women)
• Sometimes these spots can also appear on places like the elbows and knees.

However, it is not just in these places, but these `Acanthosis Nigricans` spots can appear anywhere on the body.

Is this contagious? Is it dangerous?

A question that many people have is whether this is a contagious disease. No, not at all. `Acanthosis Nigricans` is not a contagious disease. You cannot catch it from another person, nor can you catch it from someone else. So don't worry about it.

Next, is this dangerous? Actually, if you take this skin change called `Acanthosis Nigricans` alone, it is not dangerous. That is, these spots will not cause you much harm. But, the most important thing is, sometimes these spots can be a sign of some other medical condition inside our body. That is, even if these spots are visible on the surface, the cause may be some problem inside the body. That is, it is important to treat the underlying cause.

Therefore, if you notice any unusual dark spots or discoloration on your skin, you should definitely see a doctor for advice. You may be referred to a dermatologist. They will then perform the necessary tests, tell you what the cause is, and what treatment is needed.

Who is more likely to develop `Acanthosis Nigricans`? Is this a sign of diabetes?

Actually, `Acanthosis Nigricans` can develop in anyone. Even a healthy person can develop these spots. However, some people are at a higher risk of developing it. Let's see who they are:

• For people who are overweight, that is, those who are obese (obese). This is a major risk factor.
• If someone in the family has had `Acanthosis Nigricans` before (genetics).
• For those with slightly darker skin tones.
• For some ethnic groups (although this is not very relevant to our country, it is something mentioned according to World Health Organization information).

A question that many people are asking now is, 'Does having these spots mean I have diabetes?'

To be clear, not everyone with `Acanthosis Nigricans` has `Diabetes Mellitus` or `Prediabetes`. However, it can be a strong sign of diabetes or `Prediabetes`.

`Prediabetes` means that your blood sugar level is slightly higher than normal, but not yet high enough to be diagnosed with diabetes. This is like a warning sign. If you make lifestyle changes during this `prediabetes` phase, you have a good chance of preventing diabetes from developing.

So, if you have `Acanthosis Nigricans` spots, it is very important to see a doctor and have your blood sugar levels checked. This will help you determine if you have diabetes or `Prediabetes`. If you do, your doctor will be able to provide you with the necessary treatment and advice.

How common is this condition `Acanthosis Nigricans`? What causes it?

Acanthosis Nigricans is a relatively rare skin condition. However, it is more common in people who are obese. One study found that about 50% of people who were twice their ideal body weight had Acanthosis Nigricans.

Now let's see what are the main causes of `Acanthosis Nigricans`. There is not one cause, but several reasons can affect this:

• Conditions associated with high insulin levels in the blood (`Insulin resistance`): This is the main cause. People with obesity, prediabetes, and diabetes mellitus can develop insulin resistance. Simply put, when the body's cells do not respond properly to insulin, the pancreas produces more insulin. This excess insulin helps skin cells grow faster, causing these dark spots.
• Certain medications: For example, birth control pills and medications like corticosteroids.
• Hormone-related diseases: Hormonal imbalances such as thyroid disease, Addison's disease, hypothyroidism, or other disorders of the pituitary gland.
• For those taking growth hormone therapy.
• Congenital: This means that a person can be born with this condition, but this is very rare.
• Genetics: If someone in the family has the condition, others may be more likely to develop it.

Usually, the symptoms of `Acanthosis Nigricans` appear very slowly, sometimes over months or even years. However, if these spots appear suddenly, very quickly, it can be a sign of cancer, although rarely. Therefore, if you notice such a rapid change, you should see a doctor without delay.

What are the symptoms of `Acanthosis Nigricans`? How is it diagnosed?

As we have discussed a little earlier, the main symptoms of `Acanthosis Nigricans` are:

• Brown or black spots or patches on the skin.
• The skin in the area where the spots are located may feel velvety and slightly thicker. Even though it feels smooth to the touch, the skin may feel thicker.
• Sometimes small bumps (`skin tags`) appear on the skin.
• Itching. Not everyone gets itchy, but some people may experience itching around these spots.
• Rarely, a foul odor may emanate from the areas where the stains are.

Remember, these symptoms usually appear slowly, over time. Again, if these symptoms appear suddenly, very quickly, see a dermatologist immediately. This could be a sign of cancer (but remember, this is very rare).

Okay, so how do doctors diagnose this condition `Acanthosis Nigricans`?

Usually, when you go to see your doctor, they will ask you about your symptoms, your medical history (whether you have other illnesses, what medications you take, etc.). Then they will examine your skin. In most cases, these steps alone can help you determine whether you have `Acanthosis Nigricans` or not.

However, sometimes further tests may be needed to determine the exact underlying cause. Such tests include:

• Blood work: This can confirm or rule out underlying conditions like diabetes. For example, your blood sugar and insulin levels can be checked.
• Skin biopsy: This is done very rarely. It is usually done only when the diagnosis is not clear.

Will this `Acanthosis Nigricans` get better on its own? Can it be reversed? What are the treatments?

A question that many people have is whether these spots will go away on their own. In fact, `Acanthosis Nigricans` does not get better on its own. However, it does not always require medical treatment. That is, if there is no underlying medical condition causing these spots, you can decide whether to treat those dark spots or not. Some people may not care much about their appearance and may not treat them.

So, can this be reversed? That is, can the spots be removed? Yes, treatment usually produces good results. The skin becomes brighter, but sometimes the dark spots may not disappear completely. But you can see a significant reduction.

Treatment for Acanthosis Nigricans depends on the cause.

The key is to treat the underlying condition (e.g. diabetes, hormonal problems). Doing so will likely improve these skin problems as well.

In particular, weight loss, exercise, and a nutritious diet can help reduce insulin levels in the blood. This will improve the condition of the skin. In some cases, the spots may even disappear completely.

In addition, there are other treatments that doctors recommend:

• Prescription creams: These should only be used on medical advice.
• Treatments such as laser therapy or dermabrasion: These can reduce skin thickness.
• Antibiotics: Eliminate odor or discomfort.
• Retinoids: Helps brighten the skin.
• If you are taking any medication that is causing `Acanthosis Nigricans`, stop or change it (this should also be done on medical advice).

It is very important that you do not use over-the-counter or prescription creams for dark spots without consulting your doctor. They may not work, and may even irritate your skin and make the condition worse.

How to manage `Acanthosis Nigricans`? Can it be prevented?

If your Acanthosis Nigricans condition is related to elevated insulin levels (i.e., due to factors such as obesity and diabetes), controlling your weight and following a healthy diet can help prevent or reduce the appearance of these dark spots.

Here are some other steps you can take to prevent this situation:

• Managing other medical conditions (e.g. thyroid problems, diabetes) that may be associated with `Acanthosis Nigricans` means getting the right treatment for those conditions.
• Avoid taking medications that may cause or worsen `Acanthosis Nigricans` (e.g., some birth control pills) or change them as directed by your doctor.

What is the health status of people with `Acanthosis Nigricans`?

Acanthosis Nigricans is not a dangerous or harmful condition. People with this condition can live normal, healthy lives.

However, again, it is essential to properly manage underlying medical conditions (e.g. diabetes, obesity, hormonal problems) that may cause `Acanthosis Nigricans`.

Also, if dark spots appear suddenly, see a doctor immediately. It is important to be concerned about this, as it can be a sign of cancer, although rare.

When should you see a dermatologist for `Acanthosis Nigricans`?

Simply put, if you notice any changes in your skin, a new spot, or a change in color, even if it seems minor, it's best to see a doctor or dermatologist for a checkup. Sometimes, even if it seems minor, it can be a sign of a problem.

Since `Acanthosis Nigricans` can be a sign of `Prediabetes` or `Diabetes`, it is very important for your health to talk to your doctor, get the necessary tests done, and receive the appropriate treatment.
