13. Tumoral chromoblastomycosis: a rare manifestation with typical complementary exams
Abstract: Chromoblastomycosis is a chronic subcutaneous fungal infection caused by traumatic implantation of dematiaceous fungi in the skin. The clinical presentation is usually a verrucous plaque lesion and the diagnosis is confirmed by the visualization of muriform bodies at direct examination or at the histologic study. This report describes a rare case o

14. Clinical and demographic profile of chromoblastomycosis in a referral service in the midwest of São Paulo state (Brazil)
Chromoblastomycosis is one of the most frequent deep mycoses found in rural populations. This cross-sectional, retrospective and descriptive study was conducted with cases of chromoblastomycosis diagnosed throughout 20 years. A higher prevalence was observed among White male rural workers, with an a

15. A case of extensive chromoblastomycosis from North India
A case of extensive chromoblastomycosis of the right leg and thigh with verruciform to nodular lesions evolving rapidly over five years duration is reported. The diagnosis was confirmed by visualizing pathognomonic pigmented muriform bodies with unique septate hyphae and mycological culture yielding Fonsecaea pedrosoi.

16. Chromoblastomycosis: an exuberant case
Chromoblastomycosis is a chronic subcutaneous mycotic infection caused by dematiaceous saprophytic moulds. The most frequently isolated agent is Fonsecae pedrosoi. This article reports a case of a man from the Amazon region in Northern Brazil who presented with a lesion of 12 months' duration, which gradually increased in size until covering the majority of

17. Cromoblastomicose no Maranhão: uma abordagem microbiológica, ambiental e molecular
The chromoblastomycosis (CBM) is a chronic fungal infection of skin and subcutaneous tissue caused by several melanized fungi of Chaetotrhyales order. Fonsecaea pedrosoi is the major causative agent of the disease. This study aimed to evaluate the clinical and epidemiological aspects of patients with CBM and phenotypic and genotypic characterization of the a

18. Secretion of five extracellular enzymes by strains of chromoblastomycosis agents
As atividades gelatinase, urease, lipase, fosfolipase e DNase de 11 agentes da cromoblastomicose constituídos por amostras de Fonsecaea pedrosoi, F. compacta, Phialophora verrucosa, Cladosporium carrionii, Cladophialophora bantiana e Exophiala jeanselmei foram analisadas e comparadas. Todas as amostras apresentaram atividade urease, gelatinase e lipase. A a

19. Avaliação do tratamento da cromoblastomicose experimental utilizando vacina de DNA (DNA-hsp65)
Chromoblastomycosis (CBM) is a chronic worldwide subcutaneous mycosis, caused by several dimorphic, pigmented dematiaceous fungi. Patients with the disease are still considered as therapeutic challenge, mainly due to its recalcitrant nature. There is no treatment of choice for this neglected mycosis, but rather several treatment options. Itraconazole and ter

20. Bacillus subtilis induces morphological changes in Fonsecaea pedrosoi in vitro resulting in more resistant fungal forms in vivo
Interactions among microorganisms may be the cause of morphological modifications, particularly in fungal cells. The aim of this work was to examine the changes that occur in cells of the fungus Fonsecaea pedrosoi after in vitro co-culturing with Bacillus subtilis and to explore the results of this interaction in vivo in an experimental murine infection. B.

21. Experimental murine chromoblastomycosis obtained from Fonsecaea pedrosoi isolate cultured for a long periodt
The present study aimed to describe F. pedrosoi propagules capable of causing chronic murine disease. Several changes in F. pedrosoi hyphae were identified in fungal cells cultured for a long period. Optical microscopy found many rounded cells with double-rigid melanin-rich walls. Terminal and intercalary chlamydoconidia were also frequently observed. Analys

22. Respostas polares à infecção pela cromoblastomicose antes e após as terapias
Este estudo avaliou pacientes portadores de cromoblastomicose, sendo feita uma categorização clínica em dois grupos, de acordo com a forma clínica da lesão dermatológica: o primeiro composto por indivíduos com lesões elevadas e o segundo formado por casos com lesões planas, com biópsias realizadas antes e depois dos tratamentos. Através de critér

23. Cromoblastomicose: à procura do modelo experimental murino. / Chromoblastomycosis: searching for experimental murine model.
This study was prompted by the lack of a satisfactory chronic infection animal model for studies of experimental chromoblastomycosis and the fact that very little is known about the infective fungal forms of Fonsecaea pedrosoi. First, we investigated the infective potential of different mycelial forms of F. pedrosoi, hyphae, conidia and conidiogenous cells,

24. Determinação das concentrações plasmáticas e teciduais de itraconazol em pacientes com cromoblastomicose / Determination of the plasmáticas and teciduais concentrations of itraconazol in patients with cromoblastomicose
Chromoblastomycosis is a subcutaneous mycosis caused by deployment transcutaneous of several species of dematiaceous fungi, that is, melanized fungi. Considering the incidence of this disease in the state of Pará and the resulting morbidity of patients affected, with economic and social repercussions, it was made to the optimization of therapeutic schemes a
