Answer

Complications vary depending on the etiology of acanthosis nigricans (AN). Appearance of acanthosis nigricans during childhood usually is associated with a benign condition, and no important sequelae are described.

Adult-onset acanthosis nigricans is more worrisome, and an underlying malignancy must be ruled out. However, most cases of adult-onset acanthosis nigricans are benign and often are associated with insulin resistance.
