Onychomycosis of the Great Toes
Onychomycosis of the Great Toes

    This photo shows onychomycosis of the great toenails. The right toenail shows classic distolateral (a distal subungual) onychomycosis (DLO), whereas the left toenail likely began as DLO and progressed to dermatophytoma (dense collection of hyphae that appears as a linear streak).
