Abstract

Acne keloidalis nuchae (AKN) is a chronic inflammatory dermatosis of the scalp that primarily affects young men with Afro-textured hair and skin phototypes IV–VI. Its pathogenesis involves an immune response against follicular antigens, leading to perifollicular inflammation, papules, pustules, and hypertrophic plaques. Despite its clinical relevance in populations of African descent, AKN remains underrepresented in dermatological literature. This report aims to contribute to the understanding of the disease by documenting clinical, trichoscopic, and histopathological findings in a clinical case, emphasizing the role of follicular curvature as a structural and genetic factor in disease predisposition.
