Methods: A cross-sectional study of 52 cases was conducted after obtaining ethical committee approval. All affected nails were subjected to clinical observation, onychoscopy, potassium hydroxide (KOH), and fungal culture.  Results: We studied 34 females and 28 males, with a mean age of 47.2 ± 13 years, with clinically suspected toe and fingernail onychomycosis, of whom 44 (88.5%) had a confirmatory KOH or culture, mostly with the distal lateral subungual onychomycosis subtype and caused by Candida, Fusarium, and Trichosporon. Yellow or brown chromonychia, onycholysis, distal irregular termination, rough longitudinal white edge/trachyonychia, opacity, and linear white striae were the main onychoscopic findings in this and previous studies, whereas a shallow layered appearance was a new finding. Fungal melanonychia (9.6%) and blue&#8211;red globules (3.8%) were also identified in onychoscopy. There was some correlation between onychoscopic findings and the fungus cultured from the nail plate.  Conclusion: Onychoscopy can be considered a non-invasive diagnostic tool to contribute to the diagnosis of onychomycosis, as KOH examination and culture have low sensitivity. Its correlation with the causative agent could lead to a better diagnosis and facilitate the right choice of the antifungal.]]></p></abstract>
<abstract abstract-type="short" xml:lang="pt"><p><![CDATA[Resumo  Objetivos: O objetivo principal do presente trabalho foi a descrição dos padrões onicoscópicos em pacientes com suspeita clínica de onicomicose e secundáriamente correlacioná-los com padrões onicoscópicos específicos. os tipos clínicos de onicomicose, bem como os organismos causadores.  Métodos: Estudo transversal de 52 casos, após aprovação do comitê de ética. Todas as unhas afetadas foram submetidas a observação, onicoscopia, KOH e cultura para fungos.  Resultados: Neste estudo, foram incluídas 34 mulheres 28 homens, com idade média de 47.2 ± 13 anos, com suspeita clínica de onicomicose em dedos dos pés e unhas das mãos, dos quais 44 (88,5%) apresentaram KOH ou cultura confirmatória, a maioria com o subtipo DLSO e causada por Candida, Fusarium e Trichosporon. Achados onicoscópicos previamente descritos foram frequentemente observados (cromoníquia amarela ou castanha, onicólise, bordo áspero branco/traquioniquia, opaciade da lâmina ungueal e estrias brancas lineares), mas um aspecto com camadas superficiais foi um novo achado. Melanoníquia fúngica e glóbulos vermelho-azulados também foram identificados na onicoscopia. Houve alguma correlação entre os achados onicoscópicos e o fungo cultivado da lâmina ungueal.  Conclusão: A onicoscopia pode ser utilizada como auxiliar diagnóstico não invasivo em casos em que exames como o exame de KOH e a cultura apresentam baixa sensibilidade. Sua correlação com a identificação fúngica pode levar a um melhor diagnóstico e facilitar o início da escolha correta dos agentes antifúngicos.]]></p></abstract>
