TLDR Dissecting cellulitis of the scalp is a condition that causes inflammation and scarring on the scalp, mainly affecting African-American men, and can lead to permanent hair loss.
Dissecting cellulitis of the scalp (DCS) is a severe form of neutrophilic cicatricial alopecia predominantly affecting African-American men, characterized by inflammatory cystic nodules, plaques, and sinuses that lead to permanent scarring and hair loss if untreated. The condition begins with follicular occlusion, similar to hidradenitis suppurativa, acne conglobata, and pilonidal cysts, and progresses through stages of pustules, nodules, and sterile abscesses. Genetic, hormonal, and environmental factors, along with neutrophil activity and microbiota, are implicated in its pathogenesis. Early treatment can result in partial hair regrowth, while advanced stages show distinctive trichoscopic features such as double-bordered 3D yellow dots and linear scars.
