Resumo: Palmoplantar pustulosis (PPP) is a chronic and relapsing disease of the palms and soles, which tends to be difficult to treat. Clas sically it was described as a subtype of psoriasis. Nowadays it is regarded as a separate entity, although plaque-type psoriasis affects concomi tantly many patients with PPP. A link between allergic contact dermatitis (ACD) and PPP has been described, and the former may encompass a potential to perpetuate the latter. Hereby we report two cases of difficult to treat plantar pustulosis. Underneath the dermatosis’s refractive nature was an allergic sensitization to potassium dichromate and cobalt chloride. Leather shoes and leather insoles were commonly worn, and both allergens are employed by the leather industry. Clinical remission was achieved in both cases with allergen eviction. Patch testing must be considered in cases of PPP without response to treatment. If relevant sensitization is found, allergen eviction measures are mandatory.

Classi camente era descrita como um subtipo de psoríase. Actualmente é considerada uma entidade distinta, embora psoríase em placas afecte con comitantemente muitos doentes com PPP. Uma relação entre dermite de contacto alérgica (DCA) e PPP já foi descrita, e a primeira acarreta um potencial de perpeptuar a última. Aqui descrevemos dois casos de pustulose plantar de tratamento díficil. Subjacente à natureza refractária da dermatose, encontrava-se uma sensitização alergénica ao dicromato de potássio e ao cloreto de cobalto. Sapatos e palmilhas de cabedal eram comumente usadas pelas doentes, e ambos os alergénios referidos são utilizados na indústria do cabedal. Remissão clínica foi atingida em ambos os casos com evicção alergénica. O testes epicutâneos devem ser considerados em casos de PPP refractários ao tratamento. Se for demonstrada sensibilização relevante, medidas de evicção alergénica são obrigatórias.Sociedade Portuguesa de Dermatologia e VenereologiaRepositório do Centro Hospitalar Universitário de Lisboa Central, EPENeves, JBrasileiro, AMendes-Bastos, P2023-10-13T14:20:11Z20212021-01-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10400.17/4717engJ Port Soc Dermatol Venereol. 2021;79(2):173-17410.29021/spdv.79.2.1313info:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2023-10-15T06:33:08Zoai:repositorio.chlc.min-saude.pt:10400.17/4717Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T20:35:47.200837Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
