Dissecting cellulitis of the scalp presents as multiple firm, dome-shaped papules, which may coalesce to form plaques and nodules.69 Abscesses and sinus tracts may also be observed. The vertex and occipital area are most commonly affected. The disease is predominantly detected in men of African descent between 20 and 40 years of age. It may occur in association with acne conglobata, hidradenitis suppurativa (follicular occlusion triad), and pilonidal cysts (follicular occlusion tetrad).69,70

Dissecting cellulitis of the scalp (DCS) is a chronic inflammatory condition characterized by recurrent nodules, abscesses, and sinus tracts. It usually starts as simple folliculitis with occlusion of follicular openings mainly on the scalp vertex, followed by perifollicular pustules and painful fluctuant nodules releasing a purulent discharge. With time, lesions evolve into plaques embedding interconnected nodules, abscesses, or draining sinus tracts, resulting in cicatricial tissue.
Hair weave dermatitis

This patient's history and exam is consistent with dissecting cellulitis of the scalp (DCS). This dermatologic condition is predominantly seen with specific hair grooming practices, such as the use of chemical relaxers, heat straightening, tight braiding, and weaving, which can cause scalp irritation and follicular damage.
Approach to treatment of refractory dissecting cellulitis of the scalp: a systematic review
Published in Journal of Dermatological Treatment, 2021
Dissecting Cellulitis of the Scalp (DCS) is a primary neutrophilic scarring alopecia that predominately affects African American males in the 2nd and 3rd decades of life. Patients often present with painful nodules, abscesses, and permanent alopecia which may progress to extensive involvement of interconnected draining sinuses, leading to significant morbidity in more severe disease [1]. Standard therapies often incorporate the use of antibiotics and topical or intralesional steroids but these are often only effective at controlling limited disease in milder presentations [2].

Dissecting cellulitis of the scalp (DCS), also known as perifolliculitis capitis abscedens et suffodiens (PCAS) or Hoffmann disease, is a rare condition mostly occurs in black males aged 20 to 40 years. The disease presents with suppurative nodules, interconnecting sinuses, and patchy hair loss. Deep follicular occlusion may be the most important pathology in DCS.

Several other skin conditions, such as acne, pilonidal cysts, and dissecting cellulitis of the scalp have also been reported to be associated with HS [27–30]. The exact mechanisms linking these various diseases have not been defined in detail but may be linked by systemic inflammation induced by HS.
