Your Guide to Acanthosis Nigricans


Acanthosis nigricans is a skin condition that gives areas of the skin a thick, velvety appearance. It usually affects body folds, such as the armpits and neck.

Acanthosis nigricans can affect people of any age or race, but it’s more common in people who are overweight.

What causes acanthosis nigricans?

The cause of acanthosis nigricans isn’t known. However, it has been linked to high levels of insulin in the body, which may be caused by:

diabetes – type 2 diabetes is the most common form of diabetes and tends to develop in adults over 40; people with type 1 diabetes don’t produce any insulin

obesity – excess weight can increase the risk of type 2 diabetes

endocrine disorders – including an underactive thyroid (hypothyroidism) and Cushing’s syndrome, where the adrenal glands produce too much cortisol, a hormone that regulates metabolism

Rarely, acanthosis nigricans may be caused by some types of cancer.

Acanthosis nigricans is a skin condition that causes dark patches to appear on the folds and creases of the skin. These patches are often referred to as velvety plaques, and they can range in color from brown to black. The most common areas affected by acanthosis nigricans include the back of the neck, groin, armpit and elbow. Acanthosis nigricans is not considered to be a serious medical issue, but it can have some very uncomfortable symptoms and side effects that are more than just cosmetic.

Acanthosis nigricans is usually caused by an underlying medical condition, such as diabetes or obesity. It can also be the result of taking certain medications, such as birth control pills or high blood pressure medication. In addition, acanthosis nigricans can be caused by genetics.

Causes: Acanthosis nigricans is caused by a number of factors such as insulin resistance, genetics (familial type), pregnancy, oral contraceptive pills, pituitary tumors and certain medications like nicotinic acid and birth control pills.

Symptoms: The symptoms include brown-to-black pigmentation of the skin in body folds that may be itchy. There can be thickening of affected areas with a velvety texture to touch.

Treatment: The treatment includes weight loss, avoiding triggers like oral contraceptive pills and corticosteroids and use of topical retinoids for mild cases. Medications like acitretin (Soriatane), metformin (Glucophage) and pioglitazone (Actos) may help prevent acanthosis nigricans from getting worse.

Acanthosis Nigricans (AN) is a skin condition that causes dark, thick and velvety like skin in body folds and creases. It also causes similar dark patches on the neck or body. Acanthosis nigricans can be a sign of insulin resistance and prediabetes.

If you have AN, it doesn’t necessarily mean that you have diabetes or any other serious health problem. But if you do have diabetes or prediabetes, AN could be an early sign that your blood sugar levels are higher than they should be. The earlier you detect this, the more you can do to prevent serious complications such as heart disease and nerve damage.
