Background: Acne keloidalis nuchae (AKN) is a scarring folliculitis found predominantly among men of African descent. It could present as pustules, papules or keloidal eruptions usually at the occiput of the scalp and has been associated with certain aetiological factors. Aim: The aim of the study was to determine the prevalence and possible aetiological factors of AKN in the University of Port Harcourt Teaching Hospital (UPTH). Methods: It was a 3-year retrospective study conducted in the Dermatology Clinic of the UPTH, from 2014 to 2017, where folders of patients who were diagnosed with AKN by dermatologist were retrieved and reviewed. Results: The prevalence of AKN was 1.7%. Male patients were predominantly affected with a male-to-female ratio of 21:1. The age range of the cases was from 18 to 51 years, with a mean ± standard deviation of 27.31 ± 7.01. Majority of the subjects had a history of clean-shaven hair (80.6%). Other possible predisposing factors were friction from collars (48.4%) and shaving of the hairline at the occiput during haircuts (64.5%). Conclusion: Despite the low prevalence of AKN, its social impact is glaring; therefore, more emphasis should be laid on the aetiological factors and management to improve the quality of life of the affected patients.
