onychomycosis caused by scytalidium dimidiatum.we report a case of onychomycosis caused by scytalidium dimidiatum (syn., hendersonula toruloidea) in a patient who did not live in an endemic area. this nondermatophyte mold may produce disease indistinguishable from dermatophyte fungi, but it does not respond to current systemic antimycotic therapy. distal subungual onychomycosis, lateral onycholysis followed by lateral nail plate invasion, and chronic paronychia are common nail presentations.19968698921
nail infections.the increasing prevalence of onychomycoses, along with the wider range of organisms now recognized as potential pathogens, necessitates the accurate laboratory identification of the specific fungus involved. although the majority of infections still are caused by dermatophyte and candida species, many other nondermatophyte molds, such as scytalidium dimidiatum, have been shown to be common agents of disease in certain geographic areas. it is well recognized that infections by nondermatophytes su ...19968821156
subcutaneous phaeohypomycosis caused by scytalidium dimidiatum in the foot of an immunosuppressed host.the authors present a case report of a subcutaneous phaeohypomycosis of the foot in an immuno-suppressed patient. the lesion was caused by scytalidium dimidiatum, a dematiaceous fungus, which has only been reported to cause three previous similar lesions. to our knowledge, this is the first reported case of this fungus causing a deep-seated mycoses in the united states. a review of the literature concerning this organism is also presented.19968872760
molecular taxonomy and gc/ms of metabolites of scytalidium hyalinum and nattrassia mangiferae (hendersonula toruloidea).ardra of ribosomal genes confirmed that the hyphomycete scytalidium hyalinum is identical to the coelomycete nattrassia mangiferae (hendersonula toruloidea, with arthroconidial synanamorph scytalidium dimidiatum). s. hyalinum may be just a melanin-less cultural mutant of s. dimidiatum. this explains why the two species are regularly found in the same patient population as agents of human dermatomycosis. two strains from plant sources were found to be identical to the human strains in its-rflp pa ...19979229334
scytalidium dimidiatum and lecythophora hoffmannii: unusual causes of fungal infections in a patient with aids.immunocompromised patients are susceptible to infections by fungi that seldom cause disease in humans. we describe a human immunodeficiency virus-infected patient who had simultaneous infections with two fungi which are rare causes of serious infection: lecythophora hoffmannii, causing chronic sinusitis, and scytalidium dimidiatum, causing skin lesions, lymphangitis, and lymphadenitis. the clinical and pathologic findings are discussed.19979350765
nondermatophyte causes of onychomycosis and superficial mycoses.compared to dermatophytes, nondermatophytes that may cause distal and lateral subungual onychomycoses are aspergillus species, acremonium species, fusarium oxysporum and scopulariopsis brevicaulis. white superficial onychomycosis may be caused by nondermatophyte species, for example, acremonium species, aspergillus terreus, other aspergillus species and fusarium oxysporum. nondermatophyte molds such as scopulariopsis brevicaulis may uncommonly result in cutaneous infections. scytalidium dimidiat ...19969504061
