ED70.51 Dissecting cellulitis

International Classification of Diseases for Mortality and Morbidity Statistics, 11th Revision, v2024-01

Dissecting cellulitis is a destructive inflammatory disorder of the scalp characterised by widespread perifolliculitis with dermal abscess and sinus tract formation and extensive scarring. It occurs predominantly in black males aged between 18 and 40 years. It may be associated with hidradenitis suppurativa and acne conglobata (follicular occlusion triad), and with pilonidal sinus. Painful swellings develop around the vertex of the scalp and coalesce to form irregular undulating oedematous ridges and furrows. With time an extensive network of sinuses discharging pus may develop. Progressive scarring and permanent alopecia ensue.
