Acanthosis Nigricans is a benign dermatologic condition in which velvety grey-brown or black plaques develop on the skin. It generally occurs in areas of skin folding such as the back of the neck, armpits, or groin.
It is associated with a variety of endocrine disorders such as Addison's Disease, Cushing's Disease, and hypothyroidism. Rarely, acanthosis nigricans occurs in the setting of cancer or in association with other uncommon genetic syndromes. The most common cause, however, is insulin-resistant states such as diabetes mellitus. In addition, there is an association with obesity, itself a contributing factor to insulin resistance.
The exact cause of acanthosis nigricans is poorly understood. It is thought that high levels of insulin (as seen in diabetic patients) stimulate growth receptors in certain skin cells, leading to the characteristic hyperpigmented plaques. Acanthosis nigricans treatment is generally affected by addressing the underlying cause, most commonly obesity or elevated blood sugar. The simplest and most effective means of combating these problems are diet and exercise.
Acanthosis Nigricans Natural Cures
Decreasing overall caloric intake while maintaining a low-fat, high-fiber diet will help patients lose weight. This, in turn, will help reduce blood sugar levels. The addition of an aerobic exercise program to a balanced diet will help to further aid weight loss and blood sugar reduction.
Occasionally, if patients are unable to achieve satisfactory results with these first-line acanthosis nigricans treatment strategies, medications may be required to assist in maintaining normal blood sugar levels. As weight falls and blood sugar normalizes, the condition generally resolves.
[YEA] For those with Acanthosis Nigricans, Camphorated Oil will bring better circulation to the splotches on your skin. It might take a long time, maybe 1 to 2 years or longer, but try that. I used it for stretch marks and a scar and they went away in 2 years. I have a silky smooth new skin in those places now!

Thought this might be of some interest. I had embarrassing dark thick patches of skin under my arms, my neck, and my thighs as a child (noticed more so as I entered puberty.) Was always told I didn't wash enough. I WAS NOT OVERWEIGHT. It was horrible. Tried expensive medical creams, everything, to no avail. As I got older ... it simply went away. It went away when I was overweight.
I have two children, a girl and a boy, and they both acquired it about the same age as I was.
I would have never had it diagnosed correctly had it not been for an Army doctor who had seen many different things in practicing medicine all over. I did acquire diabetes later in life, after this went away. And after it went away, I acquired terrible scalp psoriasis which I have to do this day. We think my dad's brother had both acanthrosis nigricans AND psoriasis. He was not overweight.
Guess they are both autoimmune conditions in common ... Just an interesting fact to add to the fodder.

[YEA] A good, healthy diet and exercise regimen will get rid of acanthosis nigricans. I've had it since I was a teenager, but didn't know what it was until I saw a dermatologist in my twenties. I was at 230 pounds at that time, so I focused on taking care of my body and lost 55 pounds. The acanthosis nigricans disappeared.
So, the solution? Take care of yourself!Posted by Justsayin (Toronto, Ontario, Canada) on 10/09/2011
I'm pretty sure that I now know what I have Acanthosis Nigricans. My neck, cheeks (face), under arms and inner thighs are black and my skin is caramel. Those areas are not only black but like thicker and really I've tried every lotion and nothing works.
After reading that this is caused by insulin resistances which I think I might also have, I almost lost it. There are images online where they've done test with people who have Acanthosis Nigricans and put them on a strict diet and the Acanthosis Nigricans vanished.
I am going to start a 1200 calorie diet and 2hrs of cardio every day. I might start with just one hour of cardio and then one hour of anaerobic exerciser and work my way up to the 2hrs. I am also doing Jillian Michael's 30-Day Shred and will post my results in about 30days to see if anything had changed.
I though I was going to have this for ever and to think that I just need to lose weight and cut out my bad foods and this will go away is crazy!
Please people do your research everything is out there =)Replied by Lou

[BETTER BUT NOT CURED] Quite by accident, we found that mineral spirits is a cosmetic quick fix (wipe gently) for Acanthosis Nigricans, but not a cure. And that the condition will show itself again after 2-3 weeks.
