ABSTRACT

Background: Worldwide recent reports point towards a rising prevalence of onychomycosis in the pediatric population, especially among adolescents. Dermatophytes are the most common etiologic agents.
Material and methods: We carried out a retrospective review of the last 12 years, comprising 332 medical records from children with clinical suspicion of onychomycosis. We analyzed the following variables: gender, age, predisposing factors, affected nails, other concurrent superficial mycoses and potassium hydroxide direct examination and culture.
Results: A total of 233 onychomycosis cases were identified, cases constituted 33% of superficial mycoses of children seen at our unit. Two thirds were adolescents with no significant difference among the sexes. Toenails were more affected (94%) than fingernails (4.2%) with distal and lateral subungueal onychomycosis being the most common clinical presentation. In 70% of cases infection was caused by dermatophytes (mainly Trichophyton rubrum).
Conclusions: Onychomycosis constitute 33% of superficial mycoses among children seen at our medical facility. We confirm a rise in prevalence, toenails were the most common (94%) and had a dermatophytic etiology (70%). We suggest to all physicians caring for children and adolescents, to become familiar with diagnostic and therapeutic tools for this type of mycosis.
