    TLDR Acne keloidalis nuchae is a chronic skin condition more common in African men, causing itchy or painful bumps and can lead to permanent hair loss if not treated early.
    Acne keloidalis nuchae (AKN) is a chronic condition primarily affecting African men, with a prevalence of 0.45% to 13.6% and is 20 times more common in men than women. It is characterized by papules, pustules, and keloid-like masses in the occipital and nuchal regions, with contributing factors including androgens, infections, trauma, and ingrown hairs. The exact pathogenesis is unclear but may involve genetic predisposition, hair texture, androgens, and autoimmune reactions. Symptoms include itching or pain, progressing to nodules and permanent hair loss. Early treatment is key and includes antibiotics, corticosteroids, cryotherapy, surgery, and laser therapy. Prognosis hinges on early treatment to prevent permanent hair loss, and avoiding known triggers can prevent new lesions.
