Acne keloidalis nuchae in Asian: A single institutional experience

Abstract

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.

Frequency of the Types of Alopecia at Twenty-Two Specialist Hair Clinics: A Multicenter Study

“…Regarding gender, patients consulting with AKN, FD and DCS were most frequently males, while patients consulting with traction alopecia, CCCA, FFA, FAPD and LPP were most frequently females, in accordance with the literature [7,9,[14][15][16][17][18][19][20]. The most frequent alopecias in both genders were AGA followed by AA.…”

Acne Keloidalis Nuchae – Case Report

“…Collagen fibers are like those in hypertrophic scarring rather than those in real keloids. Also, histopathological examination can reveal different stages of inflammation in one lesion (13).…”

“…Laser therapy should be considered for the hair removal and/or softening of the keloidal plaques (17,18). Several authors have reported that laser hair removal is an option to prevent relapsing folliculitis (13). If pustules and draining sinuses are present and bacterial culture is positive, oral antibiotics should be administered in addition to topical antibiotics (19).…”

Acne keloidalis in an Asian female patient

“…In fact, few cases of AK in women have been reported in the literature . AK in patients of other ethnicities, particularly Asian patients, is less common . AK normally develops from firm, skin‐colored papules and pustules most often on the occipital region of the scalp extending to the posterior region of the neck.…”
