Acne Keloidalis Nuchae

Overview

Acne keloidalis nuchae (AKN) is a chronic inflammatory condition that causes firm, keloid-like papules, pustules, and plaques on the back of the neck and occipital scalp. Despite its name, it is not true acne and is not related to keloid formation. It is most common in men of African descent and is thought to be related to hair follicle irritation and inflammation.

Key Symptoms

Firm, dome-shaped papules and pustules on the nape of the neck
Keloid-like, raised, thickened plaques that may merge together
Itching, tenderness, or pain in the affected area
Scarring alopecia (permanent hair loss) in affected areas
May develop draining sinuses or abscesses in severe cases
Lesions may be skin-colored, pink, or hyperpigmented

Affected Areas

Nape of the neck, Occipital scalp, Posterior hairline

Care Instructions

Avoid close shaving, tight collars, and friction on the back of the neck.
See a dermatologist early for treatment to prevent scarring and progression.
Topical or intralesional corticosteroids can reduce inflammation.
Topical or oral antibiotics may be prescribed for active pustules.
Laser hair removal can help prevent recurrence in early-stage disease.
Surgical excision may be necessary for large, fibrotic plaques.
