Acne keloidalis nuchae in the armed forces

Acne keloidalis nuchae (AKN) is a chronic inflammatory skin disease characterized by the development of keloidlike papules, pustules, and plaques on the occipital scalp and posterior neck following mechanical trauma and irritation. First-line therapy involves avoidance of aggravating factors including short and frequent haircuts. Medical treatments-from topical and intralesional steroids, oral antibiotics, and UV light to laser and surgical excision-have demonstrated varying degrees of efficacy. The active-duty military population faces unique challenges in the treatment of AKN because personal appearance and grooming standards restrict avoidance of the very factors that promote this disease process. In this population, early identification and treatment are critical to reducing overall patient morbidity and ensuring continued operational and medical readiness. This article reviews the clinical features, epidemiology, and treatments available in the management of AKN, with a special focus on the active-duty military population.
