Acne Keloidalis Nuchae
Cather McKay, MD
Acne keloidalis nuchae (AKN) is a skin condition that starts with acne-like bumps around hair follicles on the back of the neck and lower scalp. The bumps may itch or hurt, and may or may not have pus. Over time firm scars similar to keloids form and hair loss may occur.
AKN mainly affects black men but can occur in other ethnicities and rarely in women. The cause of AKN is not fully understood. Inflammation starts around hair follicles, leading to trapped hairs which cause more inflammation and scarring. AKN is often mistaken for razor bumps or an infection from the barber. AKN is not an infection and is not contagious. A board-certified dermatologist can make a diagnosis of AKN by examining the area.
