White Piedra by Trichosporon ovoides in Southeastern Brazil: Report and Brief Literature Review
Abstract
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.
