RESUMO
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.

In the United States, the Family Case Study is a tool used in family medicine to teach students about clinical problems and the effects of illness on the patient and the family. Because the Family Case Study is not well known in Japan, the purpose of this paper was to introduce the Family Case Study on the basis of our experiences and to describe its implementation in the Department of Family Medicine of the University of Michigan Medical School. Although the Family Case Study must be adapted for Japan, we urge its use as a practical means of learning about family medicine and the concept of the biopsychosocial approach through practical learning experiences.
