Summary: Folliculitis decalvans and lichen planopilaris have been considered two distinct cicatricial alopecias. However, biphasic presentation of folliculitis decalvans - lichen planopilaris in the same patient has been recently described, therefore raising the doubt if they are two distinct entities or a continuous phenotypic spectrum.We describe the case of a man who presented clinical, trichoscopic, and histopathological features of both entities. Moreover, we discuss current theories about the pathogenesis of the two diseases and their coexistence in the same patient. The recognition of similar cases allows to optimize the approach and treatment.

No entanto, a apresentação bifásica da foliculite decalvante - líquen plano pilar num mesmo paciente foi recentemente descrita, levantando a dúvida se são duas entidades distintas ou um espectro fenotípico contínuo.Descrevemos o caso de um homem que apresentou características clínicas, tricoscópicas e histopatológicas de ambas as entidades. Discutimos as teorias atuais sobre a patogénese das duas doenças e a sua coexistência no mesmo paciente. O reconhecimento de casos similares permite otimizar a abordagem e o tratamento.Sociedade Portuguesa de Dermatologia e Venereologia2021-12-27T00:00:00Zjournal articleinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://doi.org/10.29021/spdv.79.4.1389oai:ojs.revista.spdv.com.pt:article/1389Journal of the Portuguese Society of Dermatology and Venereology; Vol 79 No 4 (2021): October - December; 361-364Revista da Sociedade Portuguesa de Dermatologia e Venereologia; v. 79 n. 4 (2021): Outubro - Dezembro; 361-3642182-24092182-2395reponame:Repositórios Científicos de Acesso Aberto de Portugal (RCAAP)instname:FCCN, serviços digitais da FCT – Fundação para a Ciência e a Tecnologiainstacron:RCAAPenghttps://revista.spdv.com.pt/index.php/spdv/article/view/1389https://doi.org/10.29021/spdv.79.4.1389https://revista.spdv.com.pt/index.php/spdv/article/view/1389/939Copyright (c) 2021 Journal of the Portuguese Society of Dermatology and Venereologyinfo:eu-repo/semantics/openAccessMarcos-Pinto, AnaRoda, AngelaSoares-de-Almeida, LuísOliveira Soares, Rui2022-10-06T12:35:20Zoai:ojs.revista.spdv.com.pt:article/1389Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireinfo@rcaap.ptopendoar:https://opendoar.ac.uk/repository/71602025-05-28T10:31:33.679314Repositórios Científicos de Acesso Aberto de Portugal (RCAAP) - FCCN, serviços digitais da FCT – Fundação para a Ciência e a Tecnologiafalse
