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.

Mãe e filha apresentando nódulos diminutos, em torno de 1 a 2 mmde diâmetro, coloração branco-amarelada na haste dos cabelos, há cerca de 6 meses. Assintomáticas. 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. O tratamento de escolha foi o corte dos cabelos associado a champô de cetoconazol 2%.Sociedade Portuguesa de Dermatologia e Venereologia2019-07-12T00:00:00Zjournal articleinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://doi.org/10.29021/spdv.77.2.1038oai:ojs.revista.spdv.com.pt:article/1038Journal of the Portuguese Society of Dermatology and Venereology; Vol 77 No 2 (2019): April / June; 157-160Revista da Sociedade Portuguesa de Dermatologia e Venereologia; v. 77 n. 2 (2019): Abril / Junho; 157-1602182-24092182-2395reponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAPporhttps://revista.spdv.com.pt/index.php/spdv/article/view/1038https://doi.org/10.29021/spdv.77.2.1038https://revista.spdv.com.pt/index.php/spdv/article/view/1038/780Ferreira, Flávia ReginaPollo, TalitaPereira, Marina Thereza FogoBueri, Margareth Neila Pratsinfo:eu-repo/semantics/openAccess2022-10-06T12:35:10Zoai:ojs.revista.spdv.com.pt:article/1038Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T16:11:09.291794Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
