This is known as acanthosis nigricans, a brown to black, poorly defined, velvety hyperpigmentation of the skin. It is usually found in body folds, such as the posterior and lateral folds of the neck, the armpits, groin, and other areas.
Acanthosis nigricans typically occurs in individuals below the age of 40 years, may be genetically inherited, and is associated with obesity or disorders of the endocrine glands in many conditions, particularly:
• states with insulin resistance, such as diabetes mellitus: normally, the tissues and organs in the body respond to insulin by taking up sugar into the cells; in states of insulin resistance, however, the response becomes very weak and so the pancreas is forced to produce more insulin to incite response. Ancanthosis nigircans occurs because of too much insulin.
• excess circulating androgens, which are male hormones produced by the adrenal gland (a small gland found on the top of the kidney), particularly Cushing's disease, acromegaly, polycystic ovarian disease (in women)
• Addison's disease (insufficiency in the adrenal gland function) and hypothyroidism (poor thyroid gland function)
Of note, acanthosis nigricans that is associated with endocrine dysfunction occurs and progresses more slowly, is less widespread, and the patients often suffer from obesity. This type is also known as "Acanthosis nigricans type III".
The majority of cases of acanthosis nigricans are associated with obesity and otherwise idiopathic. This is likely because of insulin resistance, and more likely to occur in people with darker skin tone. This is also called "Pseudo-Acanthosis Nigricans", or "Type 3 Acanthosis Nigricans".
Acanthosis nigricans has been linked to the use of nicotinic acid, steroids, and other drugs. This is also known as Type 4 Acanthosis nigricans.
Another acanthosis nigricans variant is the familial acanthosis, which typically presents at birth or appears during childhood.
Because of this skin appearance and because you are overweight, you need to be screened for diabetes: if you do not have full blown diabetes or you’re prediabetic, you may profit from lifestyle changes to help prevent progression into diabetes, like weight loss and exercise.
