[Trichophyton rubrum onychomycosis with secondary Aspergillus versicolor infection in a 12-year-old girl: successful topical therapy with terbinafine-urea ointment].

CASE REPORT: A 12-year-old with a functional circulatory disturbance had toe nail onychomycosis caused by Trichophyton rubrum. There were no other underlying diseases.

THERAPY AND OUTCOME: Oral therapy with terbinafine 125 mg once weekly in addition to ciclopirox nail lacquer was ineffective. Two years later the disease worsened and A. versicolor was found in pure culture. A preparation of 10% terbinafine HCl in a 20% urea ointment (Onychomal®) applied daily for 4 weeks, then once weekly resulted in complete cure after 7 months.
