Abstract Background: Alopecia areata is a highly frequent disease with an impact on quality of life and several treatment options with little clinical confirmatory evidence. Objective: To disseminate the recommendations of Brazilian dermatologists with expertise in the treatment of alopecia areata. Methods: Eight specialists with expertise in alopecia areata from different university centers were appointed by the Brazilian Society of Dermatology to reach a consensus on its treatment. Based on the adapted DELPHI methodology, the relevant elements were considered; then, an analysis of recent literature was carried out and the consensus was written down. Consensus on the management of alopecia areata was defined with the approval of at least 70% of the panel. Results/Conclusions: Intralesional injectable corticotherapy was considered the first option for localized disease in adults. In extensive cases with signs of activity, systemic corticosteroid therapy should be considered and can be used together with immunosuppressants (corticosteroid-sparing agents). The use of an immunosensitizer (diphencyprone) is an option for stable long-term cases. Evaluation of side effects is as important as the rate of hair regrowth.

A poroqueratose é uma desordem da queratinização epidérmica caracterizada por placas anulares com centro atrófico e bordas hiperqueratóticas, e inclui um grupo heterogêneo de desordens que são na sua maioria herdadas de forma autossômica dominante. O presente caso refere-se a uma paciente feminina de 5 anos de idade, com poroqueratose de Mibelli confirmada histologicamente. A raridade desta desordem, a exuberância clínica e o caráter destrutivo das lesões, o acometimento facial e mucoso pouco usuais nesta forma de poroqueratose e o início na infância precoce motivaram este relato.

Porokeratosis is a disorder of epidermal keratinization characterized by annular plaques with an atrophic center and hyperkeratotic edges, and includes a heterogeneous group of disorders that are mostly inherited in an autosomal dominant form. This report describes a 5 year-old female patient, with porokeratosis of Mibelli confirmed histopathologically. The rarity of this disorder, its clinical exuberance and the destructive character of the lesions, as well as the facial and mucosal involvements, unusual in this form of porokeratosis, and also its onset in early childhood motivated this report.
