It can also be caused by acanthosis nigrans, a skin condition in patients with diabetes, polycystic ovarian syndrome, but which can also be seen in overweight persons. There are medications one can use - but first one should exclude possible medical causes. Cortisone, uric acid, salicylic acid and isotretoin creams may be used depending on the cause.
