Acanthosis nigricans associated with endocrine dysfunction is more insidious in its onset, is less widespread, and the patients are often concurrently obese. Higher than normal insulin levels in the blood stream cause the growth of darkened skin over certain areas of the body. No skin treatment will get rid of AN. Acanthosis nigricans may lighten up and possibly go away by treating the root cause, insulin resistance, but it can take months or years to do so.

This is likely because of insulin resistance and more likely to occur in darker-skinned persons. Most typically it will be present as a horizontal band on the forehead, but may also appear as perioral hyperpigmentation, periorbital hyperpigmentation, or generalized facial skin darkening.

Malignant acanthosis nigricans is most commonly associated with gastrointestinal adenocarcinomas, as well as genitourinary cancers such as those of the prostate, breast, and ovary. Other cancers, such as those of the lung, stomach, and lymphoma, are occasionally associated with acanthosis nigricans.

This is most commonly insulin -mediated activation of IGF receptors on keratinocytes , as a result of hyperinsulinaemia or insulin resistance , as seen in diabetes mellitus.

Increased circulating IGF may lead to keratinocyte and dermal fibroblast proliferation. If no clear cause is obvious, it may be necessary to search for one. Blood tests, an endoscopy , or X-rays may be required to eliminate the possibility of diabetes or cancer as the cause.
