Abstract

Background & Objectives: Dermatophytosis is an emerging problem with increased morbidity in many patients. These infections are seen more in tropical countries. Overcrowding, low socio- economic actors, humidity and poor hygiene are the pre- disposing factors for the fungal infection. Dermatophytosis is a superficial fungal infection which is caused by 40 species of 3 different genera: Trichophyton, Epidermophyton and Microsporum of family Arthrodermatacacea. These organisms are keratinophillic and has affinity towards keratin rich structures such as skin, hair and nails and causes keratin degradation. The aim of the study is to identify most common clinical type of dermatophytosis and most common organism causing the disease. Methods:This was a cross- sectional study conducted between March 2021 to September 2022 in the department of Dermatology, venereology and Leprosy of a tertiary care centre. Patients who came under the inclusive criteria were taken taken into the study after taking informed consent. Detailed history is taken followed by which sample is collected for KOH, Calcofluor and culture from the affected area. Results:In this study, most common age group affected are between 31- 40 years with male predominance. Lower socio- economic status people are more affected. Mixed site involvement is seen in 68.18 % individuals with most common site to be affected is neck (55. 45%). Co-morbidities such as Diabetes, hypertension and Thyroid is seen in few. In this study, KOH mount positive was seen in 67.27 %, calcofluor white in 84.54 % and culture in 51.81% individuals. Most common diagnosis was found to be Tinea corporis with Tinea cruris (42.73%). Most common organism isolated from culture positives were Trichophyton mentagrophytes (24.55%), followed by Trichophyton rubrum (22.73%), Trichophyton tonsurans (2.73%) and Trichophyton violaceum (1.81%) Interpretation & Conclusion:In this study, most common type was tinea corporis with tinea cruris. Most common dermatophyte isolated from the specimens was Trichophyton mentagrophytes.
