Acanthosis nigricans is a physical finding of the skin that appears to be a marker for insulin resistance. Because of the association of insulin resistance and type 2 diabetes, acanthosis nigricans may also be a marker for type 2 diabetes. Some states have recommended statewide screening for acanthosis nigricans. However, this has led to a large referral of children to pediatric endocrinologists. Presented is a schema for primary care physicians and school nurses to use as a guideline for referral of children with acanthosis nigricans.
