ABSTRACT

Background: tinea cruris, a common dermatophytosis, accounts for 5% of dermatology consultations. It primarily affects men between their third and fifth decades of life. Globally, Trichophyton rubrum is the most prevalent causative agent, followed by Trichophyton mentagrophytes and Epidermophyton floccosum.
Objectives: to present the epidemiological data and identify the most common causative agent of tinea cruris cases seen at the Mycology Section of a general hospital in Mexico City.
Methods: this was a retrospective, cross-sectional, descriptive, and observational study involving 66 patients suspected of tinea cruris. These patients were evaluated over a 10-year period and referred to the Mycology Section at Dr. Manuel Gea González General Hospital.
Results: of the 66 included patients, 61 had a positive direct examination for filaments ± spores, and 34 had a positive dermatophyte culture. T. rubrum predominated (48.48%), followed by T. tonsurans (1.51%) and E. floccosum (1.51%). The predominant sex was male, with 49 patients (74.24%), and the mean age was 45.7 years. The most prevalent comorbidities were HIV (12.12%) and diabetes (9.09%). One patient (7.57%) was on antifungal therapy, and one (7.57%) was undergoing immunosuppressive therapy.
Conclusions: this study reports that tinea cruris predominantly affected males between their fourth and sixth decades of life, with a variable duration of evolution. The most prevalent causative agent was T. rubrum .
