Tinea  pedis and onychomycosis are common superficial skin infections and are seen in tropical and subtropical regions. Tinea pedis is distinguished by lesions on the sole of the foot, while onychomycosis affects the morphological structure of the nail. It is recognized that the main microorganisms related to these two diseases are  Trichophyton rubrum  and  Trichophyton interdigitale .. These conditions are an important cause of medical consultation and despite not having a significant mortality rate, they have a high emotional and physiological effect, and can even cause stigmatization and social exclusion. Nail changes generate pain when walking or standing for a long time, with limitation of mobility or when performing some activities; They are common among athletes, especially soccer players. The objective of this bibliographic review is to describe the clinical manifestation of tinea pedis and onychomycosis, their pathogenesis, the main pathogens involved and their prevalence in soccer players. For the development of this topic review, a literature search was carried out in English and Spanish for articles published between 2015 and 2021. The search was performed in electronic databases such as Pubmed, NCBI, Science Direct and Journal using the keywords validated in DeCS. With the present review it was evidenced that onychomycosis manifests itself in three characteristic forms and it was established that the prevalence of onychomycosis in soccer players is 60.7%  and tinea pedis of 36.9 % .
