Acanthosis nigricans

Acanthosis nigricans is said to be a kind of skin condition that is characterized by areas of dark, velvety discoloration on body folds and creases. The affected skin may become thickened. Most often, the acanthosis nigricans affects the areas around the armpits, groin, and the neck.

The skin changes of acanthosis nigricans generally occur in those people who are obese or may have diabetes. Those children who develop the condition are at a higher risk of developing type 2 diabetes.

 Symptoms of having Acanthosis Nigricans

Skin changes are the only signs of acanthosis nigricans. One may notice dark patches on neck, thickened, velvety skin in the body folds and creases — typically in your armpits, groin, and dark pigmentation around neck. The skin changes generally appear slowly. The affected skin might also have an odor or an itch.

 Causes of Acanthosis Nigricans

Acanthosis nigricans has been associated with several disease such as:

·         Hormonal disorders. Acanthosis nigricans generally occurs in those people who have hormonal disorders such as underactive thyroids, ovarian cysts, or problems with the adrenal glands.

·         Insulin resistance. Most of the people who have acanthosis nigricans may have also become resistant to insulin. The Insulin is a hormone that is secreted by the pancreas which allows the human body to process sugar. Insulin resistance may eventually cause type 2 diabetes.

·         Cancer. Acanthosis nigricans sometimes occurs with the lymphoma or when a cancerous tumor is growing in an internal organ, like the stomach, colon, or the liver.

 When to see a doctor

Consult a doctor if you notice the changes in the skin — especially if these changes appear suddenly. One may have another underlying condition which might need treatment.
