Introduction
Acanthosis Nigricans (AN) is a skin condition characterized by dark, thick, and velvety patches of skin. It commonly affects body folds such as the neck, armpits, groin, elbows, and knees. While the condition itself is not contagious or harmful, it can be a sign of underlying health issues such as insulin resistance, obesity, hormonal disorders, or, in rare cases, certain cancers.
