Overview
Acanthosis nigricans is a skin condition characterized by dark, velvety patches of skin. The affected skin may also feel thicker than normal. The patches usually appear in skin folds and creases, such as the neck, armpits, groin, and under the breasts.Acanthosis nigricans can occur in people of any age, but it is most commonly seen in those who are overweight or have insulin resistance or diabetes. It can also be a side effect of certain medications, including oral contraceptives, growth hormone, and corticosteroids. In rare cases, acanthosis nigricans can be a sign of an underlying cancer, such as stomach or liver cancer.The diagnosis of acanthosis nigricans is usually based on the appearance of the skin. In some cases, a biopsy may be necessary to rule out an underlying cancer.Treatment of acanthosis nigricans involves addressing the underlying condition, such as losing weight or treating diabetes. There are also topical creams that can improve the appearance of the skin. In some cases, laser therapy or chemical peels may be used to remove the affected skin. It is important to consult a dermatologist for proper diagnosis and treatment.
