Acne keloidalis nuchae, a type of folliculitis involving the back of the neck, is common in black men, although rare cases have been reported in patients of other ethnicities. We analyzed the clinicopathological features of acne keloidalis nuchae in 17 Asians. Patients’ age at the time of presentation ranged from 20 to 69 years. Most patients experienced the disease over 2 years (range, 3 months–20 years); follow-up data were available for 11 (65%) patients (range, 2–95 months). Nine (53%) patients had comorbidities, but none had a history of other skin disease or a family history of acne keloidalis nuchae. Macroscopically, seven (41%) patients had multiple erythematous pustulopapular lesions, and 10 (59%) had a single large plaque. Histopathologically, deep scarring folliculitis containing naked hair shafts was identified. In all cases, inflammation was most severe in the upper two-thirds of the dermis, and the differences in pustulopapular and plaque lesions were more prominent in the peri-inflammation area. Of the seven patients with plaque lesions treated with steroids alone or steroids and cryotherapy, three experienced plaque reduction. Acne keloidalis nuchae occurring in Asian patients frequently present with typical clinicopathological features, and therefore in spite of very low incidence the diagnosis of this disease entity should be considered in idiopathic scarring folliculitis of the posterior neck.

“…Multiple exacerbating factors such as improper hair cutting practices, trauma, friction (rubbing from shirt collars and helmet), heat, and humidity are found to be associated with AKN. [3] Other potential contributory factors include altered immune response, autoimmunity, androgens, and seborrhea. is condition was also suggested to be a marker of metabolic syndrome by Verma and Wollina.…”

Extensive donor site keloids in follicular unit extraction hair transplantation

et al. 2017

View full text Add to dashboard Cite

Hair transplantation, a generally regarded as a safe surgical modality for the treatment of androgenetic alopecia, is not without its potential risks and complications. A case of an extensive keloid formation at donor site following follicular unit extraction is discussed. Hair transplant surgeons should be aware of this significant potential complication, especially in patients having previous keloidal tendencies to avoid such disastrous outcomes.
