Infections caused by black fungi

Cerebral phaeohyphomycosis: Case report

“…There has been much confusion regarding the terminology for infection caused by dematiaceous fungi 8 . Two terms are commonly used to describe mycoses caused by dematiaceous molds and yeasts, that is, chromoblastomycosis and phaeohyphomycosis 1,8 . Chromoblastomycosis is an infection in which highly pigmented fungi form sclerotic bodies, that is, muriform cells.…”

“…Chromoblastomycosis is an infection in which highly pigmented fungi form sclerotic bodies, that is, muriform cells. These fungi do not multiply by budding in the tissue 8 . On the other hand, phaeohyphomycosis is an infection in which the causative agents produce any combination of dematiaceous yeast‐like cells, hyphae or pseudohyphae in the tissue 8 .…”

“…These fungi do not multiply by budding in the tissue 8 . On the other hand, phaeohyphomycosis is an infection in which the causative agents produce any combination of dematiaceous yeast‐like cells, hyphae or pseudohyphae in the tissue 8 . Histologically, fungi in phaeohyphomycosis contain melanin in their cell walls 5 .…”

Structure, Cellular Distribution, Antigenicity, and Biological Functions of Fonsecaea pedrosoi Ceramide Monohexosides

“…However, it also suggests that these enzymes could be involved in F. pedrosoi dimorphism, although the details by which it happens remain to be elucidated. In addition, melanin expression is more intensive in sclerotic cells than in conidia and mycelia of F. pedrosoi (20). CMH structural diversity has been considered to be linked with fungal dimorphism.…”

A case of chromoblastomycosis with an unusual clinical manifestation caused by Phialophora verrucosa on an unexposed area: treatment with a combination of amphotericin B and 5-flucytosine

“…Both chromoblastomycosis and phaeohyphomycosis can be caused by the same black fungi and have various clinical manifestations, and were therefore considered to be one entity. However, phaeohyphomycosis does not show sclerotic bodies, which are chestnut brown, cross‐walled cells, commonly called ‘copper pennies’, which represent a vegetative form of the fungus 1,2 , 4 …”
