ACANTHOSIS NIGRICANS IN RELATION TO DIABETES TYPE 2 AND POLYCYSTIC OVARY SYNDROME
Acanthosis nigricans (AN) is a skin condition characterized by hyperpigmentation in areas of skin that become darker, or more pigmented, and may turn greyish, black, or brown.
These areas of skin also become thicker and may take on a velvet-like appearance. Eventually, skin lines may become deeper and more noticeable, and wart-like growths can appear. Occasionally, the lesions may become dry and pruritic (itchy) and can feel rough to the touch. Skin tags are also frequently visible in surrounding areas affected by AN. Some people will emit an unusual, bad odor, and they may experience skin changes on one side of their body only (unilateral acanthosis nigricans).
Changes to the skin typically develop slowly and they can occur anywhere, but most commonly affect the anus, armpits, genitals, groin, back, and sides of the neck. Less commonly, AN develops on the back of the knees, front of the elbows, knuckles, lips, palms of the hands, soles of the feet, and under the breasts.
The majority of cases of AN result from obesity, insulin resistance, or diabetes. It is more common in people who are of African, Caribbean, Hispanic, or Native American descent. Acanthosis nigricans skin patches occur when epidermal skin cells begin to reproduce rapidly. This abnormal skin cell growth is most commonly triggered by high levels of insulin in the blood. Weight loss and reversing insulin resistance are the most effective ways to eliminate any skin changes. It is reversible and will disappear as the cause is treated.
The prevalence of acanthosis nigricans is high in both males (46 percent) and females (58percent). Polycystic ovary syndrome (PCOS) is well-established as an insulin-resistant state, and this may account for some or all of the higher prevalence of AN among women with type 2 diabetes mellitus.
