Acne Keloidalis Nuchae – Case Report

Acne keloidalis nuchae (AKN) / folliculitis keloidalis nuchae (FKN) is a chronic inflammatory condition which involves hair follicles localized predominantly in occipital scalp and posterior neck area leading to hypertrophic scarring alopecia. We present a 59-year-old factory worker, Caucasian male with a whitish alopecic oval plaque about 10 cm in diameter in the occipital region. The peripheral part of plaque was mildly inflammated, with groups of tufted terminal hairs, while the central part showed cicatricial alopecia and discrete non-adherent dry scales. Skin changes firstly occurred 6 years earlier, as itchy papules and pustules that sometimes healed with scarring. The applied relevant diagnostic and therapeutical measures are discussed in this report.
