Abstract

Background: Vietnam is a tropical country where many dermatological diseases occur, including dermatophytosis. Diagnosis of dermatophytosis primarily relies on direct microscopic examination (KOH preparation), which may have certain limitations. Additionally, certain lifestyle habits can be associated with dermatophytosis. Objective: (1) To determine the prevalence of dermatophytosis and identify the composition species of dermatophytes from outpatients at Can Tho University of Medicine and Pharmacy Hospital; (2) To investigate some factors related to dermatophytosis from outpatients at Can Tho University of Medicine and Pharmacy Hospital. Subject and methods: The cross - sectional descriptive study was performed on 92 patients with suspicious skin lesions due to dermatophytes at Dermatology Clinic, Can Tho University of Medicine and Pharmacy Hospital from December 2023 to July 2024, and those patients had designated for fungi direct wet microscopy. Samples were examined under the microscope, inoculated on Sabouraud agar and Dermatophyte test medium for identification. Result: The prevalence of dermatophytosis was 32.6%, in which Trichophyton rubrum occupied the highest proportion (56.7%), following by Trichophyton interdigitale (26.7%), Trichophyton mentagrophytes (13.3%), and lastly, Trichophyton tonsurans (3.3%). Oily skin, frequent sweating and the history of using topical medications were related factors with dermatophytosis, with statistically significant differences (p<0.05). Conclusion: The prevalence of dermatophytosis is still quite high (mainly due to Trichophyton rubrum) and oily skin, frequent sweating, the history of using topical medications related to dermatophytosis.
