Acne keloidalis nuchae

A chronic inflammatory condition affecting the nape of the neck

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

Acne keloidalis nuchae is believed to result from a combination of follicular occlusion, chronic inflammation, and abnormal wound healing. The condition begins with the inflammation of hair follicles, leading to the formation of papules and pustules. Over time, these lesions can develop into firm, keloid-like scars.

Clinical Presentation

Patients with acne keloidalis nuchae typically present with small, firm papules and pustules on the nape of the neck. These lesions can coalesce to form larger plaques and keloid-like scars. The affected area may be itchy or tender, and in some cases, secondary bacterial infection can occur.

Diagnosis

The diagnosis of acne keloidalis nuchae is primarily clinical, based on the characteristic appearance and location of the lesions. A skin biopsy may be performed to rule out other conditions and to confirm the diagnosis.

Management

Management of acne keloidalis nuchae involves a combination of medical and surgical approaches. Topical and intralesional corticosteroids are commonly used to reduce inflammation. Antibiotics may be prescribed to treat secondary infections. In some cases, surgical excision of the lesions may be necessary.

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 consistent management are key to preventing progression and minimizing scarring.

Prevention

Preventive measures for acne keloidalis nuchae include avoiding close shaving of the affected area, using gentle hair care products, and maintaining good hygiene. Patients are advised to avoid mechanical irritation and trauma to the nape of the neck.
