          Abstract

          São descritos três casos de feo-hifomicose subcutânea, os primeiros encontrados no Estado do Pará, todos oriundos de localidades situadas a leste de Belém, nas micron-regiões do Salgado e Bragantina. O diagnóstico teve por base o reconhecimento dos parasitos em cortes histológicos, sem identificação de espécie, uma vez que todo o material disponível para exame - compreendendo as lesões completamente excisadas -, ao ser recebido, já estava fixado em formol e imprestável, portanto, para qualquer tentativa de estudo micológico. A abmidância de elementos fúngicos verificada nos tecidos, após impregnação pela prata (métodos de Grocott e de Fontana-Masson), contrastava com a dificuldade para visualizá-los em cortes não-corados ou corados por hematoxilina-eosina, fato devido certamente ao aspecto das hifas neles existentes: delgadas, de paredes finas e cor quase imperceptível.

          Translated abstract

          Three cases of subcutaneous phaeohyphomycosis from the State of Para, Brazil, are reported. This is the first time that this form of phaeohyphomycosis is described in Northern Brazil. The etiologic agents could not be isolated, and the diagnosis in all cases was stablished only on histopathological basis, particularly through the demonstration of fungal elements in tissue sections. Hyphal fragments and vesicidar cells were very numerous and conspicuous in special (Grocott and Fontana-Masson methods) stained sections, in contrast to their apparent scarcity in routine hematoxilin-eosin preparations. The difference was certainly due to the aspect in the latter of the invasive tissue forms: the thin-walled and light brown pigmented organisms stained poorly and were veiy difficult to distinguish from the tissue components.

          Chromoblastomycosis and phaeohyphomycosis: new concepts, diagnosis, and mycology.

          The nomenclature for the mycoses caused by dematiaceous fungi should represent the combined clinical, pathologic, and mycologic relationships exhibited in the diseases. Chromoblastomycosis encompasses chronic, localized infections of the cutaneous and subcutaneous tissues that contain sclerotic bodies and histologically show hyperkeratotic pseudoepitheliomatous hyperplasia with keratolytic microabscess formation in the epidermis. In contrast, phaeohyphomycosis is a collective term for a heterogeneous group of mycotic infections that contain dematiaceous yeastlike cells, pseudohyphae-like elements, hyphae, or any combination of these forms in tissue. The terms superficial, cutaneous and corneal, subcutaneous, and systemic phaeohyphomycosis are proposed for the major categories of phaeohyphomycosis. The term chromomycosis is rejected for mycoses caused by the dematiaceous fungi.
