Resumo: | The rarity of this entity and the exuberance of these cases of white piedra, associated with the complete documentation (including species identification) motivated this report. Mother and daughter presenting asymptomatic tiny white-yellowish nodules, around 1 to 2 mm in diameter, on the hair shaft, for about 6 months. The hot and humid weather and the habit of using conditioning creams may have been determining factors of the infection. Analysis of the hair strands under an optical microscope, culture and microculture and mass spectrometry (MALDI-TOF/MS) concluded the diagnosis of white piedra by Trichosporon ovoides. It resolved with a short haircut associated with ketoconazole 2% shampoo. |

O clima quente e húmido e o hábito do uso de cremes recondicionadores podem ter sido fatores determinantes da infecção. A análise dos fios ao microscópio óptico, a cultura e o microcultivo e a espectrometria de massas (MALDI-TOF/MS) concluíram o diagnóstico de piedra branca por Trichosporon ovoides.
