Trichosporon species are commonly known as causative agents of skin infections and also responsive in some other systemic and disseminated diseases, especially in immunocompromised patients and those with leukemia or lymphoma. Chronic cutaneous infections with Trichosporon have been reported in non-immunocompromised patients, too.

This study is a case report of tinea pedis caused by Trichosporon asahii in an immunocompetent 39-year-old man who was a member of the military force with continuous wearing of army boots during his daytime work. In April of 2019, after visiting a dermatologist, he was referred to the Ghaem medical mycology laboratory of the Department of Health, Rescue and Treatment of Iran Police Force in Tehran. Clinical symptoms were scaling and erythematous patches on his left foot with intensive itching for four-months. In the laboratory, macroscopic and microscopic examination using direct 15% KOH wet mount was carried out as well as culture methods on fungal media (Sabouraudchr('39')s dextrose agar with and without cycloheximide and chloramphenicol). According to microscopic observation and appearance of culture media colonies, the diagnosis was Trichosporon genus as the fungal agent of disorder. Molecular method analysis (PCR) using amplification of ITS region with universal primers (ITS1 and ITS4) and sequencing identified Trichosporon asahii as a causative species of the disease. The patient was treated with topical clotrimazole (twice/day) and oral fluconazole (150 mg/day) for four weeks, and recovered.

The conditions that cause the feet to be exposed to excessive sweating, moisture and darkness for a long time (wearing shoes and army boots for a long time); increase the risk of skin fungal infection. Therefore, full respect for an individual healthy manner seems to be essential.

Tinea pedis is one of the most prevalent fungus infections in humans. Since moist conditions probably favor growth of the fungus, the role of swimming pools has been well established in the propagation of dermatophytic foot infections. Since swimming pools are the most important places for flare-up of clinical symptoms in asymptomatic persons and propagation of infections,and also the treatment of tinea pedis is time-consuming and expensive therefore, it is better to try for prevention of infections. The aim of this study was to determine the prevalence of tinea pedis in swimmers of the west pools of Tehran city in 2007. Yet preventive measures were taken by detecting and referring infected swimmers to medical centers. Patients and This cross-sectional study was carried out in 2007, in ten swimming pools selected randomly from the swimming pools of regions under the supervision of Iran University of medical sciences. Feet and toe clefts of 2500 regular swimmers, who went to the swimming pool at least once a week, were examined by a dermatologist and from the lesions clinically suspected to be tinea pedis, samples were taken and sent to the laboratory of mycology for direct smear and culture. Of the 2500 swimmers(1850 males and 650 females) ranging from 5 to 70 years of age, 16 individuals (0. 64%) including 12 males (0. 65%) and 4 females (0. 62%) showed positive culture for dermatophytes The infection was more prevalent in swimmers with an age range of 46-55 years. The main dermatophytes involved in tinea pedis in swimmers were: Epidermophyton floccosum 8 cases (50%), Trichophyton mentagrophyte, var. interdigital 4 cases (25%), and Trichophyton rubrum 4 cases (25%). Other organisms isolated from culture media included Candida, Corynebacterium minutissimum, Aspergillus niger, bactiria and saprophytes. Our study revealed that tinea pedis was not frequent among swimmers.
