Complications

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.

Prognosis

The prognosis for patients with malignant acanthosis nigricans is often poor. The associated malignancy frequently is advanced, and the average survival of these patients is approximately 2 years.

Patient Education

Patients should be instructed that acanthosis nigricans is not a skin disease per se, but rather a sign of an underlying problem. If a patient does have acanthosis nigricans on the basis of insulin resistance, which is the most common reason, treatment of the metabolic abnormality may lead to improvement of the appearance of the skin. Dietary changes and weight loss may cause the acanthosis nigricans to regress almost completely.
