Acne Keloidalis Nuchae

Acne Keloidalis Nuchae (AKN) is a chronic inflammatory condition that primarily affects the nape of the neck. It is characterized by the formation of papules, pustules, and keloid-like scars. This condition is most commonly seen in individuals with curly hair, particularly those of African descent.

Pathophysiology

The exact cause of Acne Keloidalis Nuchae is not fully understood, but it is believed to be related to folliculitis, which is the inflammation of hair follicles. The condition begins with small, itchy papules that can progress to pustules and eventually form keloid-like scars. These scars are firm, raised, and can be disfiguring.

Clinical Presentation

Patients with Acne Keloidalis Nuchae typically present with:

Small, itchy papules on the nape of the neck
Progression to pustules and nodules
Formation of keloid-like scars
Possible secondary infection

The lesions are often painful and can lead to significant cosmetic concerns for the patient.

Diagnosis

Diagnosis of Acne Keloidalis Nuchae is primarily clinical, based on the characteristic appearance of the lesions. A skin biopsy may be performed to rule out other conditions such as pseudofolliculitis barbae or hidradenitis suppurativa.

Treatment

Treatment options for Acne Keloidalis Nuchae include:

Topical and oral antibiotics to reduce inflammation and infection
Topical corticosteroids to decrease inflammation
Intralesional steroid injections for keloid-like scars
Laser therapy to reduce scar tissue
Surgical excision in severe cases

Patients are also advised to avoid close shaving and to use gentle hair care practices to prevent exacerbation of the condition.

Prognosis

The prognosis for Acne Keloidalis Nuchae varies. While some patients may experience improvement with treatment, others may have persistent or recurrent lesions. Early intervention and adherence to treatment can improve outcomes.
