Acne Keloidalis Nuchae

Acne Keloidalis Nuchae: Description, Causes and Risk Factors:Abbreviation: AKN.Alternative Names: Acne keloidalis, keloidal folliculitis, nuchal keloidal acne.Acne Keloidalis Nuchae literally means "scarring acne of the neck." It is an unusual skin condition that commonly affects adult black males and other darker-skinned individuals with curly hair. The condition may persist for many years. AKN is most frequent found in Afro-American young adult men, and is characterized by the presence of keloid-like cutaneous lesions on the back of the scalp and neck. In the USA, AKN represents 0.45% of skin disorders affecting blacks. The prevalence of Acne Keloidalis Nuchae within their dermatology unit was 0.37%. It does also occur in other racial groups including Hispanics and Asians, but it is rarely seen in Caucasians.The exact etiology of AKN remains unknown. One postulation is that chronic irritation and inward growth of coarse curved hairs may play a role in the development of these lesions. This leads to the development of papules, which may become infected and in the long-term leads to scarring with the development of keloid lesions.Other postulated important contributory factors include constant friction from the hand, shirt collars or helmets and a short, stocky neck.Risk factors of AKN are as follows:acne keloidalis nuchaeRegular use of antiepileptic drugs.
  • Irritation of shirt's collar regularly.
  • Sometime systemic steroid therapy may cause this illness.
Symptoms:The most common signs of AKN are as follows: Posterior neck (back of the neck), occipital scalp (lower back of the scalp) lesions. Initially, lesions of AKN appear as red or pus-filled bumps, which may be tender or itchy. Over time, these inflamed bumps develop into small scars.Diagnosis:Diagnosis is based on culture and sensitivity testing of AKN pustules and draining sinuses should be considered.Treatment:Unfortunately, AKN tends to be chronic and often persists despite a variety of treatments. There is no known cure. For this reason, preventing the development of AKN is important and men of African descent should be educated about hair care practices to help prevent the onset of AKN. Topical steroids may be useful for mild disease. Some time cryotherapy may be used for the treatment of warts. This can be associated with pigmentation changes at the site and this may last for 12-18 months or permanently. Individual spots or keloids can also be surgically removed via various techniques. Apart from this certain types of laser therapy may also be used in treatment of AKN.Disclaimer:The above information is general information.
