Acne keloidalis nuchae (AKN) also known as folliculitis keloidalis nuchae (FKN) is a chronic form of scarring folliculitis seen mostly in men of African descent. The term AKN is commonly used even though the condition is not a keloid, and the affected individuals do not have a tendency to develop keloids in other areas of the body. It is seen in post pubertal men and is rare after the age of 55 years. A few cases have been reported in females. which has been classified as a primary cicatricial alopecia since the exact cause of acne keloidalis (AK) remains unknown. However, a few inciting agents have been suggested which include androgens, inflammation, infection, trauma, genetics, and ingrowing hairs. AK shares some similar features with other forms of cicatricial alopecia and may occur together. Papules, pustules, and sometimes tumorous masses in the nuchal or occipital regions of the scalp hence the name “bumps” evolved in the environment. Despite its common occurrence, only a few seek help in hospital when lesions start to unsightly affect the individual’s quality of life. The presences of the keloidal lesions are more stressful compared to the resulting alopecia. Various attempts to reduce the bumps with corrosives, acids, and car engine oils lead to larger lesions or unsightly scars. Active lesions produce bleeding during haircuts. This is worrisome as a couple of individuals with active AK share shaving instruments at the barber shop and are at risk of acquiring or transmitting blood-borne infections. There is an urgent need to encourage safe shaving habits and treatment of lesions at onset so as to prevent unsightly lesions.

“…However, recurrent surgical removals may be necessary if the excisions are not carried to depths exceeding levels of the hair follicles. Although cure by radiation treatment has been used, in the single reported case, all lesional tufted hair was permanently lost at 20 months after therapy 10 . The success of laser hair removal underscores the folliculocentric nature of the disease 5, 6, 7, 8…”

“…Although cure by radiation treatment has been used, in the single reported case, all lesional tufted hair was permanently lost at 20 months after therapy. 10 The success of laser hair removal underscores the folliculocentric nature of the disease. [5][6][7][8] Histologic studies have shown that hair follicles play a central role in both triggering the disease and perpetuating it into papules, indurated plaques, and masses.…”

“…Numerous studies have shown that it is not a true keloid [1][2][3] ; when all follicular structures within the lesion are eliminated by surgery or laser, the lesion is permanently eliminated. [3][4][5][6] Millan-Cayetano et al 7 reported the use of radiation therapy (RT) in a patient with an isolated AKN lesion with no recurrence. Permanent killing of lesional hair by radiation coincided with lesion regression and permanent elimination of the disease, further supporting the folliculocentric foundation of AKN, which is resolved by focusing the treatment objective on removing hair located within the lesion.…”

“…Permanent killing of lesional hair by radiation coincided with lesion regression and permanent elimination of the disease, further supporting the folliculocentric foundation of AKN, which is resolved by focusing the treatment objective on removing hair located within the lesion. 7 We describe the use of low-dose RT to cure AKN in a patient who failed years of medical therapy and who was not a candidate for primary surgical intervention.…”
