Classically it was described as a subtype of psoriasis. Nowadays it is regarded as a separate entity, although plaque-type psoriasis affects concomitantly 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.","PeriodicalId":238976,"journal":{"name":"Journal of the Portuguese Society of Dermatology and Venereology","volume":"181 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114948401","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Gonçalo","doi":"10.29021/spdv.79.2.1394","DOIUrl":"https://doi.org/10.29021/spdv.79.2.1394","url":null,"abstract":"Introdução: Atualmente, a compreensão sobre a etiopatogenia da urticária crónica espontânea é escassa. Devido à carência de dados sobre a sua etiologia, o tratamento disponível tem apenas como objetivo o controlo sintomático, com a maioria dos doentes a serem resistentes à primeira e segunda linha terapêutica (anti-H1 de segunda geração). Tendo em conta o seu impacto no doente e o difícil controlo sintomatológico, surgiu a necessidade de investigar marcadores de resposta ao tratamento da urticária crónica espontânea. \u0000Métodos: Realizou-se uma revisão sobre biomarcadores que permitem guiar na prática clínica a escalada terapêutica destes doentes, permitindo um controlo mais eficaz e precoce da urticária. \u0000Resultados: Na urticária crónica espontânea (UCE) têm sido investigados muitos biomarcadores, mas são ainda escassos e por vezes contraditórios os resultados sobre a sua capacidade de prever a resposta à terapêutica. A maioria dos estudos é concordante na menor reatividade aos anti-H1 perante níveis de PCR ou D-dímeros elevados e nas formas de UCE autoimunes. Neste último caso, se predominarem anticorpos IgG anti-FcεRI ou anti-IgE (autoimunidade tipo IIb), os doentes habitualmente têm o teste do soro autólogo e o teste de ativação dos basófilos positivos, basopenia, eosinopenia e IgE sérica total baixa ou muito baixa, e a resposta ao omalizumab costuma ser pobre e/ou lenta, mas tendencialmente favorável à ciclosporina. Se predominar a IgE anti-self (autoimundade tipo I ou autoalergia) a IgE sérica total é normal ou elevada, na ausência dos marcadores característicos da autoimunidade IIb, e a resposta à ciclosporina é pobre, mas bastante favorável e rápida ao omalizumb. A elevação dos D-dímeros prediz uma reposta desfavorável aos três fármacos. \u0000Conclusão: Na UCE resistente aos anti-histamínicos de segunda geração, habitualmente com PCR e D-dímeros elevados, os doentes que respondem favoravelmente à ciclosporina e lentamente ao omalizumab têm normalmente uma autoimunidade tipo IIb subjacente e os doentes refratários à terapêutica com ciclosporina e que respondem rapidamente ao omalizumab têm subjacente uma autoimunidade tipo I ou autoalérgica. Estes subtipos podem ser indiretamente avaliados pelos níveis séricos de IgE total, pelos valores de basófilos e eosinófilos circulantes e pelos testes do soro autólogo e de ativação dos basófilos. Contudo, são ainda necessários mais estudos para estabelecer biomarcadores mais precisos que auxiliem na seleção da escalada terapêutica.","PeriodicalId":238976,"journal":{"name":"Journal of the Portuguese Society of Dermatology and Venereology","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121849444","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

SCC in-transit metastases are rare and predict a poor prognosis. We present the case of a 69-year-old patient with a right lower leg SCC, surgically excised with free margins. One month later, erythematous to violaceous, firm papules begin to erupt on the right lower leg, evolving to ulcerated nodules over a period of weeks. Homolateral inguinal and iliac nodal metastases were documented by percutaneous biopsy of an inguinal palpable lymph node and later documented by positron emission tomography – computed tomography (PET-CT). Given the unresectability of the disease, regional chemotherapy involving isolated limb perfusion (ILP) with melphalan and tumor necrosis factor-alpha (TNFα) was performed in order to avoid amputation. Macroscopic regression ensued, with complete resolution of all visible in-transit metastases 12 weeks after perfusion. However, a fatal outcome was observed 4 months later, due to systemic metastases. ILP is an effective and well-established technique in the treatment of advanced tumors of the extremities. Its main indications are in-transit metastases of malignant melanoma and advanced soft tissue sarcomas. However, studies have shown its effectiveness in other tumors such as locally advanced SCC. Despite the unfortunate outcome, it was possible to avoid amputation of the limb, with complete local disease remission.","PeriodicalId":238976,"journal":{"name":"Journal of the Portuguese Society of Dermatology and Venereology","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130031297","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
