Case report: onychomycosis due to Trichophyton schoenleinii

Trichophyton schoenleinii is an antropophilic dermatophyte transmitted by contact between humans. This genus is an aetiological agent of mycosis of the scalp – tinea favosa. Infections with T. schoenleinii were the most frequent dermatomycoses in Poland before the Second World War. Improvements in living conditions and hygiene after the Second World War have led to considerable decrease of infection with this fungus. We describe a patient who had a toenails involvement due to T. schoenleinii.
