Abstract

Introduction: Onychomycosis is an infection of the nail plate, bed, and matrix, leading to the gradual damage, and usually occurs in up to 50% of diseases that arise in the nail apparatus. The diagnosis of onychomycosis is made using the PASstained nail clipping technique. Dermoscopy of onychomycosis can be a useful diagnostic tool. Objective: To determine the relationship between dermatoscopic patterns and the causal agent of onychomycosis. Materials and methods: A prospective, cross-sectional, observational, and analytical study of 45 patients with suspected onychomycosis was carried out. All patients underwent direct mycological examination with KOH and culture. The most frequent dermoscopic patterns were identified and the statistical relationship with the causal microbiological agent was analyzed using the chi square test. Results: The participants in this study had an average age of 58.69 ± 14.43 years, with an age range between 30 and 89 years, 55.56% were female and 60% received outpatient care. The most frequent microbiological agent were yeasts with 64.44%. Immunosuppression was the most frequent comorbidity with 33.33%. There is a statistical relationship between the dermatoscopic patterns and the causal microbiological agent since a value of p≤0.05 was determined. Conclusion: There is a statistical relationship between dermatoscopic patterns and the causal microbiological agent.
