Clinical and epidemiologic evidence has shown acanthosis nigricans to be closely related to defective tissue utilization of insulin in a number of previously recognized (e.g., obesity, lipodystrophy, and leprechaunism) as well as recently characterized (e.g., type A and type B syndromes) disorders. This article reviews the relationship of acanthosis nigricans to these insulin-resistant states. It also focuses attention on the possibility that interaction between excessive amounts of circulating insulin with insulin-like growth factor receptors on keratinocytes and dermal fibroblasts leads to the development of acanthosis nigricans.
