Acanthosis nigricans is a common skin disorder that leads to dark, thickened, and velvety skin patches. It occurs most frequently in the folds of the body, the neck, armpits, groin, or under the breasts. Acanthosis nigricans is not harmful, but it can be a sign of an underlying process that needs to be evaluated by a dermatologist in Houston.
What Causes Acanthosis Nigricans?
Acanthosis nigricans is most commonly linked with insulin resistance, a process in which the body's cells do not respond to insulin. This is most frequently seen in people with type 2 diabetes, prediabetes, obesity, or metabolic syndrome. Other causes can include:
- Hormonal Disorders – Hormonal disorders such as polycystic ovary syndrome (PCOS), thyroid disease, or Cushing's syndrome may result in acanthosis nigricans.
- Genetics – Certain people inherit a predisposition to develop this disorder.
- Certain Medications – Some medications, such as birth control pills, corticosteroids, or high-dose niacin, may lead to the formation of darkened skin patches.
- Cancer – Occasionally, acanthosis nigricans can be associated with certain cancers, most commonly stomach or liver cancer.
Symptoms of Acanthosis Nigricans
The most noticeable symptom of acanthosis nigricans is dark, thickened, and slightly raised skin patches that have a velvety texture. The patches can develop gradually and sometimes can have an unpleasant smell or can cause mild itching. The most affected areas are:
- The posterior side of the neck
- Armpits
- Groin
- Elbows or knees
- Knuckles or fingers
Though acanthosis nigricans is not painful, its occurrence can be alarming and may indicate an underlying medical condition that needs treatment.
When to See a Dermatologist
Should you notice new changes in your skin, particularly darkening patches that grow or expand, it is crucial to consult a dermatologist. Acanthosis nigricans can be an early sign of an internal disorder like insulin resistance or diabetes. By identifying the cause, your dermatologist can refer you to the proper medical management and lifestyle changes.
