What is Acanthosis Nigricans?
Acanthosis nigricans is when your skin gets dark and feels velvety in certain areas. These dark patches often show up in folds of your skin, like on the neck, armpits, and groin. If your skin thickens and you smell something strange there, you might have this condition.
This skin issue can change how you look. The dark, rough patches aren’t just a physical problem. They might make you feel bad about your body. But, remember, these patches are a sign of something else going on in your body, like diabetes, not a problem all on their own.
Seeing a doctor is key if your skin changes. Especially if dark patches start showing up where your skin folds. A specialist or doctor can check out your skin, do some tests, and see why this is happening.
Causes of Acanthosis Nigricans
Acanthosis nigricans is a skin disorder that makes parts of the skin darker. It happens for several reasons. Knowing these reasons helps in treating the condition.
Insulin Resistance and Obesity
Insulin resistance is a key reason for acanthosis nigricans. It often links with obesity and diabetes. When the body’s cells don’t react well to insulin, it causes the skin to thicken and darken.
Hormonal Disorders
Hormonal issues are another cause. Diseases like polycystic ovary syndrome (PCOS) can mess with your hormones. This leads to dark patches on the skin. It’s important to treat these hormonal imbalances to help the skin heal.
Medications and Supplements
Some drugs and supplements have been known to cause acanthosis nigricans. These include corticosteroids, birth control pills, and some hormones. Be aware of the side effects of these medications. Talk to your doctor if you notice any strange skin changes.
Underlying Cancerous Tumor
A rare cause of acanthosis nigricans is a hidden cancer tumor. Dark skin patches can sometimes be a warning sign. If these patches appear suddenly or with other symptoms, see a doctor right away.
It’s crucial to know what causes acanthosis nigricans for proper care. By dealing with issues like insulin resistance, hormones, medications, or even cancer early, skin health improves. This also boosts general health.
Symptoms of Acanthosis Nigricans
Acanthosis nigricans shows recognizable signs, making it easier to spot. The first and most obvious one is dark, velvety patches on the skin. These patches are usually in areas like the neck, armpits, and groin. This darkened skin might also feel thicker and have a velvet-like texture.
Other things to watch for are itchiness and the growth of skin tags. These tags are small, soft, and can be the color of flesh or slightly darker. They often form a cluster near the dark patches.
Some might also notice a bad smell coming from the affected skin areas. This odor could cause social discomfort. But, keep in mind that this symptom doesn’t appear in everyone with the condition.
In very rare cases, acanthosis nigricans affects mucous membranes in the nose, mouth, or throat. These areas might show the same signs as the skin folds. If you see any unusual signs there, it’s essential to visit a doctor for a check-up.
Summary of Acanthosis Nigricans Symptoms:
- Dark, velvety patches of hyperpigmented skin
- Thickened and velvety skin texture
- Itching
- Skin tags
- Foul odor (in some cases)
- Changes in the mucous membranes of the nose, mouth, and throat (in rare cases)
Knowing these symptoms can help you take the right steps. If you think you might have acanthosis nigricans, or if you notice any skin/mucous membrane changes, see a doctor. They can give you the right diagnosis and help you manage the condition.
Diagnosis of Acanthosis Nigricans
A diagnosis of acanthosis nigricans usually starts with looking at the skin. Doctors can spot the dark, velvety patches in folds of the skin pretty easily. These patches are a key sign of the condition.
But sometimes, more tests are needed to find the real issue. Doctors might order blood tests to look for diabetes, insulin resistance, or hormone problems. These tests help doctors understand a person’s health better and what might be causing the skin changes.
On rare occasions, a skin biopsy might be done. This is to make sure it’s not another skin problem or cancer. During a skin biopsy, a small piece of the skin is taken and checked under a microscope. It can really help confirm if it’s acanthosis nigricans.
Treatment Options for Acanthosis Nigricans
After being diagnosed with acanthosis nigricans, the next step is treatment. This is focused on fixing the main issue and making the skin better. The main goal is to treat related health problems and ease symptoms.

Risk Factors and Epidemiology of Acanthosis Nigricans
Acanthosis nigricans is a skin condition found more in people who are overweight. The extra weight stresses the body and can cause this condition. It’s also more common in Native Americans, African Americans, and Hispanics.
If someone in your family had acanthosis nigricans, you might get it too. This is because of genes. Diabetes and insulin resistance can also make it more likely to appear. These problems often happen with obesity.
This condition is often seen in people under 40. But it can happen at any age. It’s not clear how many people have it, but it does affect many, especially those at higher risk.
Epidemiological Data of Acanthosis Nigricans
| Population | Prevalence |
|---|---|
| Overweight or obese individuals | High |
| Native Americans | High |
| African Americans | High |

| Diabetes and insulin resistance patients | Increased likelihood |
| General population | Estimated to affect a significant portion |
The table shows the bigger risks for acanthosis nigricans. This includes people who are overweight, Native Americans, African Americans, and Hispanics. Also, those with a family history or diabetes and insulin resistance. Knowing these risks helps people and doctors spot and treat the condition early.
Pathophysiology of Acanthosis Nigricans
The cause of acanthosis nigricans links to several key points. A main cause is insulin resistance and high insulin levels. This situation can make the skin cells thicken and darken.
Problems with hormones and growth factors also add to the start of acanthosis nigricans. They mess up how the skin cells should work. This helps form the dark, velvety patches we notice.
Studies know that insulin and insulin-like growth factors boost skin cell growth. This overgrowth of cells causes the skin to get thicker and darker. This often happens in the skin folds like the neck, armpits, and groin.
Besides insulin, other hormones like androgens and corticosteroids can also play a part. They too can make the condition worse. And add to the skin’s darkening.
The details of how all these elements work together are not entirely clear. But, scientists are working hard to understand. They are looking at the very basic building blocks to solve this mystery.
Complications of Acanthosis Nigricans
Acanthosis nigricans isn’t usually serious by itself. Yet, it could mean there are health issues. People with this condition might get type 2 diabetes, heart disease, or specific cancers.
The risk of type 2 diabetes goes up if you have acanthosis nigricans. This comes from the body not using insulin well. But you can lower this risk. How? By being active, eating right. Also, don’t forget your doctor’s advice.
Heart problems like high blood pressure are common in these cases. Acanthosis nigricans can lead to a higher chance of heart issues. To stay healthy, watch out for high cholesterol. Also, keep an eye on your weight.
Acanthosis nigricans might also point to some cancers. This is more likely with stomach or urinary cancers. And though we don’t know for sure, it’s a reason to check it out. Especially if your skin changes a lot all of a sudden.
Talking with your doctor regularly is very important. They can help keep an eye on things. This includes your health and the acanthosis nigricans. Also, try to stay fit, keep a healthy weight. If you working on that, you can avoid many issues.
Acanthosis Nigricans Complications
