Abstract:
Although dermatophytes are still the main etiologic agents of onychomycosis, some species of nondermatophytic molds and yeasts are also capable of invading the nails. Scopulariopsis (S.) brevicaulis is a nondermatophytic mold which is saprophytic fungus in soil. We report four cases of toenail onychomycosis caused by S. brevicaulis in a 42-year-old male, a 46-year-old male, a 37-year-old male, and a 64-year-old male. Three patients presented with a typical distal subungual onychomycosis and one case was proximal subungual onychomycosis. Direct microscopic examination of scrapings on the potassium hydroxide preparation revealed fungal elements in all cases. Cultures from toenail lesions of the all patients on Sabouraud dextrose agar showed a typical brown colony with powdery surface of S. brevicaulis. Numerous branched conidiophores with chains of lemon-shaped conidia with rough walled were observed in slide culture and scanning electron microscopy (SEM). We confirmed S. brevicaulis by colony, light microscopic morphology and SEM.
