Abstract

Acanthosis nigricans (AN) is a velvety, hyperpigmentation of the skin that usually occurs in intertriginous areas. AN is most commonly associated with benign disorders like diabetes, insulin resistance, endocrinopathies and exogenous medications, but can be a valid cutaneous marker of a wide range of internal malignancies, which makes it important for the physicians across specialties to have awareness about it. With an increase in the prevalence of obesity and diabetes in recent decades, the prevalence of AN has also shown a significant increase. This article will review in detail the epidemiology, pathophysiology, clinical features and treatment of acanthosis nigricans in the light of the literature
