White piedra: molecular identification of Trichosporon inkin in members of the same family.

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.
