INTRODUCTION: white piedra is a type of mycosis characterized by white to light brown nodules attached the hair shafts of genitals, axilla, eyelashes, eyebrowns, and scalp and is mainly caused by Trichosporon inkin and Trichosporon ovoides. CASE PRESENTATION: a 35 years-old female with good physical condition and good hygienic habits, who came from San Pedro Sula in Honduras, went to the doctor because of some nodules in their genital hair, asymptomatic, two months of evolution. On physical examination, it was observed that there were white-to-light brown coloured nodules measuring 1-2mm and surrounding the hair shafts. No fluorescence was detected in the hair on Wood´s light. On microscopic examination, blastoconidia and arthroconidia were observed; the culture yielded the growth of elevated yeastlike colonies; the microculture in malt extract agar showed disarticulating hyaline hyphae, partitioned appressoria, fragmented pseudohyphae, rectangular arthroconidia and blastoconidia. Through the API ID32C system, it was identified as Trichosporon inkin. The patient was treated with Isoconazole cream after her genital hair had been shaved. At the end of treatment, the exam results were negative. CONCLUSIONS: the case of a female with genital white piedra was presented and an updating on Trichosporon genus taxonomy on the basis of molecular studies. The role of T. inkin in this mycosis, and its growing importance as an agent of invasive infections in immunocompromised patients, as well as the relevance of lab diagnosis to confirm cases, were discussed.
