To present an overview of the existing epidemiological evidence regarding the occurrence of tinea gladiatorum in wrestlers and dermatophyte contamination in wrestling halls, five electronic databases including "PubMed," "Scopus," "Google Scholar," "Science Direct," and "Web of Science" were searched from inception to 30 December 2018. Studies focusing on epidemiology of dermatophytosis among wrestlers and on the presence of dermatophytes in wrestler hall were included. Data from 13 studies, 4818 wrestlers, and 391 wrestling mat samples from Turkey, Iran, and the USA (including a separate dataset for Alaska) were included. The prevalence of tinea gladiatorum in wrestlers varied from 2.4 to 90.62%, with the overall prevalence of 34.29% (95% CI 20.33-48.25). The prevalence of dermatophytes in wrestling halls varied from 0 to 56%, with the overall prevalence of 5% (95% CI 4-7). The most frequent causative agent was Trichophyton tonsurans (875/951; 92%). The most common clinical feature of dermatophytosis among wrestlers was tinea corporis (62.2%). Meta-analysis indicated significant heterogeneity of all included studies (Q = 3204.72, P < 0.001, I-2 = 99.6%). The publication bias evaluated using Egger's test was negligible (P = 0.033). The current systematic review and meta-analysis are limited by the relatively low number of published studies on tinea gladiatorum and its prevalence among wrestlers. In Conclusion, the analysis revealed a relatively high prevalence of tinea gladiatorum among wrestlers, with a paucity of evidence on dermatophytes in wrestling halls.
