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 dimidiatum (Scytalidium anamorph of Hendersonula toruloidea) and Scytalidium hyalinum may cause interdigital tinea pedis, and less frequently "moccasin foot" or plantar tinea pedis. Nondermatophytes have generally responded poorly to griseofulvin and ketoconazole. There have been reports of some nondermatophyte fungi responding to itraconazole and terbinafine.
