소아 조갑진균증 환자에 대한 임상적 고찰(2005∼2014) = Clinical Study of Onychomycosis Observed in Children (2005∼2014)

다국어 초록 (Multilingual Abstract)

Background: Pediatric onychomycosis has been previously investigated; however, the specific causative agents of onychomycosis in Korean children have not been reported. Objective: This study aimed to determine the most common causative agents of onychomycosis in Korean children. Methods: We reviewed the medical records of 149 pediatric patients (＜18 years of age) referred for fungal cultures because of a clinical suspicion of onychomycosis between 2005 and 2014 at our clinic. Patient specimens were cultured on Sabouraud`s dextrose agar with and without cycloheximide. Results: Onychomycosis was clinically suspected in 149 children. Of the 44 patients with onychomycosis, confirmed by culture, 72.7% had toenail onychomycosis, 22.7% had fingernail onychomycosis, and 4.5% had toenail and fingernail onychomycosis. The male-to-female patient ratio was 1.93：1. Fourteen (31.8%) children had concomitant tinea pedis, and 12 (27.2%) had family members with tinea pedis or onychomycosis. Distal and lateral subungual onychomycosis were the most common (68%) clinical types. Trichophyton rubrum was the most frequently isolated pathogen (66.7%), followed by Candida albicans (14.8%), Microsporum canis (11.1%), Candida parapsilosis (3.7%), and Candida tropicalis (3.7%). Candida albicans was the most commonly isolated pathogen (50.0%) in fingernail onychomycosis. Conclusion: Pediatric onychomycosis is more common than most people think. Thus, we suggest the need for a careful mycological examination of children with suspected onychomycosis. (Korean J Dermatol 2016; 54(10):781∼ 787)
