Clinicomycological Study of Dermatophytosis in a Tertiary Care Hospital in Eastern India: A Cross-sectional Study

INTRODUCTION: Dermatophytosis is a fungal infection of the skin, hair, and nails. In the past several years, it has emerged as a general public health problem in our country. Studies from different regions reveal varying patterns of etiological distribution of the disease. AIMS AND OBJECTIVES: To estimate the prevalence of different fungal species associated with dermatophytosis and to find out any possible association of the type of fungus with different clinical parameters of the disease. MATERIALS AND METHODS: This was a cross-sectional study among 311 clinically diagnosed dermatophytosis cases from a tertiary care center in eastern India. Potassium hydroxide (KOH) mount and fungal culture were done from samples of skin, hair, and nails, and various clinical parameters were analyzed. RESULTS: There was a male preponderance among cases and maximum patients belonged to third decade of life. Most common presentation was tinea corporis et cruris (39.5%). Family history was positive in 48.8% of cases. Trichophyton mentagrophytes was the most common fungal species (79.91%) grown in culture followed by Trichophyton rubrum (13.53%). Majority of patients had a mild body surface area involvement. We did not find statistically significant association of any clinical parameters with type of organism isolated. CONCLUSION: Trichophyton mentagrophytes was the most common isolated fungal species. This is in contrast to several studies where T.rubrum was the frequently found organism. There was no significant association of any clinical parameters like body surface area, number of sites, or duration of diseasewith fungal species isolated in culture.
