RESUMO
African hair shaft and pigmented scalp have unique features that challenge diagnosis in scarring alopecia. In addition, Black patients may associate 2 or more types of hair disorders. Therefore, it is imperative to understand their findings thoroughly to establish a good diagnosis. Differential diagnosis on the frontal scalp includes traction alopecia and frontal fibrosing alopecia. Disorders such as central centrifugal cicatricial alopecia, fibrosing alopecia in a pattern distribution, discoid lupus erythematosus, and lichen planopilaris usually affect the middle scalp. Folliculitis decalvans, dissecting cellulitis, and acne keloidalis nuchae are the main differential diagnosis of the posterior scalp.

Dissecting cellulitis (DC) is a chronic inflammatory primary neutrophilic scarring alopecia. It predominantly affects the vertex and occipital regions of Afro-descendent men. Female DC is uncommon, and little is known about this condition in childhood. This paper reports a pediatric female case of DC with an excellent therapeutic response to low-dose oral isotretinoin.

Dissecting cellulitis of the scalp (DCS) is a chronic inflammatory primary neutrophilic scarring alopecia, and its etiopathogenesis is yet only partly understood. DCS manifests with inflammatory nodules on the occipital scalp or vertex that may evolve to extensive confluent boggy plaques with sinus tract formation¹. predominantly affects young Afro-descendent men.Therapeutic management of DCS is often challenging1,6.

CeluliteRESUMO
Dermatologic conditions may be the subjects of potential emergency consultations, and the knowledge of their sonographic appearance can facilitate an early diagnosis and management. In this pictorial essay, the sonographic dermatologic anatomy, technique, and conditions that can be supported by a prompt sonographic diagnosis are reviewed. The sonographic signs that may help diagnose these entities are discussed with a practical approach.
