Nondermatophytic onychomycosis by Fusarium oxysporum in an immunocompetent host.

Fusarium onychomycosis is not uncommon in tropical countries but is worth reporting. We report a case of nondermatophytic onychomycosis by Fusarium oxysporum in an immunocompetent woman from Buldhana district of Maharashtra (India). Bilateral involvement of great toe nail, chronic duration and acquisition of infection due to peculiar practice of daily pasting floors with mud and dung, is interesting. The case was successfully treated with topical and oral terbinafine with a dose of 250 mg daily for 3 weeks.
