ABSTRACT

Abstract We report a rare case of subcutaneous phaeohyphomycosis caused by Cladophialophora bantiana in an immunocompetent patient in Amazonas, Brazil. This dematiaceous fungus has been mainly associated with life-threatening infections affecting the central nervous systems of immunosuppressed patients. We present the clinical, laboratory, and therapeutic aspects, and in vitro susceptibility test results for different antifungal drugs. A brief review of the cases reported in the literature over the past 20 years has also been discussed. According to the literature review, the present case is the first report of subcutaneous phaeohyphomycosis due to C. bantiana in an immunocompetent patient in Latin America.

ABSTRACT

Abstract: Psoriasis is a chronic inflammatory disease of multifactorial etiology influenced by genetic, immunological, and environmental factors. We report the case of a patient with psoriasis for more than 25 years who developed hyperuricemia and chronic tophaceous gout with unusual appearance. In psoriasis, hyperuricemia may occur by increased epidermal cell turnover, which accelerates purine metabolism and has uric acid as the product of its catabolism. The association of psoriasis with hyperuricemia can trigger the onset of gouty arthritis, and pose a greater risk of developing other inflammatory comorbidities. Therefore, it is important to periodically investigate uric acid levels in order to treat changes triggered by hyperuricemia.

ABSTRACT

FUNDAMENTOS: A pitiríase versicolor (tinha versicolor) é uma micose superficial crônica, causada por leveduras do gênero Malassezia spp. comensais das camadas queratinizadas da pele e que, sob determinadas condições ainda não esclarecidas, se torna patogênica, determinando as manifestações clínicas da doença. É uma dermatose recidivante e, mesmo após tratamento, pode deixar hipopigmentação persistente, causando problemas sociais aos indivíduos acometidos. OBJETIVO: Descrever as características clínicas e epidemiológicas de pacientes com diagnóstico de tinha versicolor atendidos em uma unidade de referência em Dermatologia (Fundação Alfredo da Matta). MÉTODOS: Estudo de série de casos em que foram detalhadas as manifestações cutâneas e as características epidemiológicas de pacientes atendidos na Fundação Alfredo da Matta com diagnóstico de tinha versicolor. RESULTADOS: Cento e dezesseis pacientes foram incluídos no estudo no período de janeiro a agosto de 2008. A maioria dos indivíduos é do sexo masculino, de cor parda, da faixa etária jovem e formada por estudantes, que apresentavam fatores predisponentes ao surgimento das manchas. Também a maioria apresentava lesões extensas e história passada da doença. CONCLUSÃO: O estudo mostrou alta proporção de indivíduos com quadros extensos e de longa duração da doença.


BACKGROUND: Pityriasis versicolor (tinea versicolor) is a chronic superficial mycosis caused by yeasts of the Malassezia spp. genus commensal of the keratinized layers of the skin. Under conditions not yet understood, it becomes pathogenic determining the clinical manifestations of the disease. It is a recurrent skin condition and persistent hypopigmentation may remain after treatment, causing social problems to those affected. OBJECTIVE: To describe the clinical and epidemiological features of patients diagnosed with tinea versicolor treated at a referral center for dermatology (Alfredo da Matta Foundation). METHODS: Case-studies in which cutaneous manifestations and epidemiological characteristics of patients diagnosed with tinea versicolor treated at Alfredo da Matta Foundation were detailed. RESULTS: One hundred and sixteen patients were included in the study from January to August 2008. Most subjects were male, of mixed ethnicity and young age. Most were students who were predisposed to the development of macules. The majority had extensive injuries and past history of the disease. CONCLUSION: The results revealed a high proportion of individuals with extensive clinical manifestations and duration of the disease.

ABSTRACT

Lacaziose é infecção crônica causada pelo fungo Lacazia loboi, originalmente descrita por Jorge Lobo (1931) em paciente oriundo da Amazônia brasileira. Manifesta-se, sobretudo, por lesões cutâneas queloidiformes. Relata-se o caso de paciente com placa eritêmato-violácea, cuja hipótese diagnóstica inicial foi de hanseníase dimorfa tuberculóide, doença também endêmica na região amazônica. Ressalta-se a importância da inclusão de formas paucibacilares de hanseníase no diagnóstico diferencial da lacaziose.


Lacaziosis is a chronic skin infectious disease caused by the fungus Lacazia loboi, which usually results in indolent cutaneous keloid-like lesions. It was first described by Jorge Lobo, in 1931, in a patient from the Amazon region. We report a case of lacaziosis, manifested by an erythematous infiltrated plaque, causing misdiagnosis with paucibacillary leprosy, since both diseases are endemic in Amazon basin.
