The first case: a 31-year-old woman was diagnosed with white superficial onychomycosis of great toe caused by <italic>Trichophyton rubrum</italic>. The treatment with 5% amorolfine once a week for 6 months resulted in full recovery (both mycological and clinical). The second case: a 42-year-old woman developed onychomycosis after the application of decorative coating on her nails; onychomycosis was caused by <italic>Scopulariopsis brevicaulis</italic>. She was treated with itraconazole pulse therapy and 5% amorolfine lacquer. She fully recovered. The third case: a 65-year-old man with total onychomycosis of 10 toes developed the skin mycosis of the left foot and lower third of the leg. He was prescribed a therapy with sertaconazole cream and 5% amorolfine lacquer. The use of 5% amorolfine lacquer was continued to prevent from recurrent dermatomycosis. Thus, the above mentioned cases are a good example of the advantages of using 5% amorolfine lacquer in the treatment of most toe onychomycosis types caused by any pathogens (dermatophytes, yeasts or molds).</p></abstract><trans-abstract xml:lang="ru"><p>В статье приведено описание трех клинических случаев успешной терапии онихомикоза стоп и микоза стоп разной этиологии с применением противогрибкового лака с 5% аморолфином. Первый случай: у пациентки 31 года был выявлен белый поверхностный онихомикоз первых пальцев стоп, вызванный <italic>Trichophyton</italic><italic> </italic><italic>rubrum</italic>. Фактором риска развития онихомикоза и микоза стоп было регулярное посещение бассейна. Терапия лаком с 5% аморолфином 1 раз в неделю 6 месяцев привела к полному выздоровлению (микологическому и клиническому). Назначение длительной профилактической терапии лаком с 5% аморолфином предупредило развитие рецидива онихомикоза стоп. Второй случай: у пациентки 42 лет развился недерматофитный онихомикоз после перманентного декоративного покрытия ногтей, вызванный <italic>Scopulariopsis brevicaulis</italic>. Она была пролечена пульс-терапией итраконазолом и лаком с 5% аморолфином. Было достигнуто полное выздоровление. Третий случай: у пациента 65 лет с тотальным онихомикозом 10 пальцев стоп развился микоз кожи левой стопы и нижней трети голени. Ему была назначена терапия кремом с сертаконазолом и лаком с 5% аморолфином. В результате терапии микоз кожи полностью разрешился. Нанесение лака с 5% аморолфином было продолжено для профилактики рецидива микоза кожи. Системная терапия не назначалась из-за высокого риска развития нежелательных явлений. Таким образом, приведенные нами случаи наглядно демонстрируют возможности применения лака с 5% аморолфином в терапии большинства разновидностей онихомикоза стоп, вызванных любыми возбудителями (дерматофитами, дрожжами и плесенями).</p></trans-abstract><kwd-group xml:lang="en"><kwd>оnychomycosis</kwd><kwd>amorolfine</kwd><kwd>Trichophyton rubrum</kwd><kwd>Scopulariopsis brevicaulis</kwd><kwd>Trichophyton interdigitale</kwd><kwd>case series</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>онихомикоз</kwd><kwd>аморолфин</kwd><kwd>Trichophyton rubrum</kwd><kwd>Scopulariopsis brevicaulis</kwd><kwd>Trichophyton interdigitale</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Sigurgeirsson B, Baran R.
