Résumé
Abstract Dissecting cellulitis is an inflammatory, chronic, and recurrent disease of the hair follicles that mainly affects young Afro-descendent men. Trichoscopy is a method of great diagnostic value for disorders of the scalp. Clinical and trichoscopic findings of dissecting cellulitis are heterogeneous and may present features common to non-cicatricial and scarring alopecia. This article presents the trichoscopic findings of dissecting cellulitis that help in the diagnosis and consequent institution of the appropriate therapy and better prognosis of the disease.

Abstract: Lichen planopilaris is a disease that appears with lymphocytic cicatricial alopecia. It is considered a follicular variant of lichen planus. The examination of affected areas shows alopecia with perifollicular erythema and scaling, revealing a predilection for hair follicles. The involvement of children is uncommon, with few reports in this population in the literature. This study presents a clinical case of a male patient of 15 years of age with characteristic lesions of lichen planopilaris.
