What is acanthosis nigricans?
Patches of darker, thick, velvety skin in creases and folds of the body. (Often the armpit or crux of the thighes). Some say it “feels like ball skin”.
Acanthosis nigricans can affect people of all races and genders. It usually appears slowly and is easy to overlook because it’s “been there forever”.
What causes it?
Acanthosis nigricans is most commonly caused by insulin resistance, diabetes, or other endocrine disorders. (Very rarely, by cancers.)
If you have acanthosis nigricans:
Please visit your doctor and point the condition out. Acanthosis nigricans is caused by an underlying health problem that needs to be addressed. If the doctor says it’s “just your weight”, ask about insulin resistance. You may need to consider a special diet lower in carbohydrates, medication, or increased exercise to manage your blood sugar. Weight loss may also help.
Long term prognosis:
If the underlying cause is treated, the patches can fade.
