Cladosporium spp. as a causative agent of white superficial onychomycosis.

White superficial onychomycosis is less common than distal subungual onychomycosis and occurs when certain fungi invade the superficial layers of the nail plate directly. Later, the infection may move through the nail plate to infect the cornified layer of the nail bed and hyponychium. It can be recognized by the presence of welldelineated opaque “white islands” on the external nail plate, which coalesce and spread as the disease progresses. At this point, the nail becomes rough, soft and crumbly. Inflammation is usually minimal in patients with white superficial onychomycosis, because viable tissue is not involved. It occurs primarily in the toenails. The most common etiologic agent in white superficial onychomycosis is Trichophyton mentagrophytes. Also, several non-dermatophyte moulds, including Aspergillus terreus, Acremonium roseogrisum (later confirmed to be Acremonium potronii) and Fusarium oxysporum, have been implicated [1]. We aimed to detect the involvement of some non-dermatophytic filamentous fungi in onychomycosis and reports on a case of onychomycosis due to Cladosporium spp. Methods
