Abstract

INTRODUCTION: White piedra is a superficial mycosis caused by the genus Trichosporon and characterized by nodules on hair shaft. METHODS: The authors report a family referred to as pediculosis. Mycological culture on Mycosel® plus molecular identification was performed to precisely identify the etiology. RESULTS: A Trichosporon spp. infection was revealed. The molecular procedure identified the agent as Trichosporon inkin. CONCLUSIONS: White piedra and infection caused by T. inkin are rarely reported in Southern Brazil. The molecular tools are essentials on identifying the Trichosporon species.INTRODUÇÃO: Piedra branca é micose superficial causada por fungos do gênero Trichosporon e caracterizado por nódulos firmemente aderidos à haste do pêlo. MÉTODOS: Os autores relatam casos familiares encaminhados como pediculose. Foram utilizados cultura em ágar Mycosel® e identificação molecular. RESULTADOS: Exame micológico revelou a infecção por Trichosporon spp. A identificação molecular demonstrou se tratar do Trichosporon inkin. CONCLUSÕES: Piedra branca e infecção pelo T. inkin são raramente relatados na região sudeste do Brasil. A identificação molecular é essencial para correta determinação de espécies no gênero Trichosporon.
