Background: This study was conducted to evaluate the occurrence of cutaneous fungal infections affecting athletes. Methods: A respectively study of superficial fungal infections in athletes was carried out during the period March 2002 to December 2006 on 656 mycologically proven cases of dermatophytosis found in athletes in Tehran. Mycological examination consisted of culturing of pathologic material followed by direct microscopic observation. Mycological cultures were carried out on Sabouraud Chloramphenicol Agar, Sabouraud Chloramphenicol and Cyclohexamide Agar, and Dermatophyte Agar incubated at 25° C for at least 28 days. Diagnosis was based on macroscopic and microscopic characteristics of the colonies. Results: We surveyed 1075 athletes suspected of having cutaneous fungal infections from 201 institutions and found that 656 (61%) were positive for fungal infections. The fungal isolates comprised Trichophyton tonsurans (56%), Epidermophyton floccosum (11.8%), Trichophyton mentagrophytes (8.9%), Trichophyton rubrum (8.3%), Trichophyton verrucosum (3.9%), Trichophyton violaceum (3.3%), Microsporum canis (2.5%), Malassezia fur fur (3.3%), and Pityrosporum oval (2%). The distribution of the lesions on the body was: trunk> groin> hair and scalp> sole and toe webs> finger nails> toe nails. Fungal infections were more commonly seen in wrestlers and aerobics.
Conclusion:The results suggest that athletic activity seems to be a predisposing factor, especially for fungal infections.
