    Abstract:
    Onychomycosis, a fungal infection of the nail is responsible for up to 50.0% of all nail diseases. Though, dermatophytes are most frequently implicated as the causative agents in onychomycosis, yeast and molds are increasingly recognized as causative pathogens. This study was aimed to know the clinical and mycological pattern of onychomycosis in eastern Nepal. Eighty-two clinically diagnosed patients of onychomycosis attending the Dermatology Outpatient department of a tertiary hospital over a period of one year were enrolled in this study. Clipping from the severely affected nail and skin scrapping from active border of the skin lesions if associated were collected from each patient and subjected to microscopy and culture for identification of fungi. The commonest affected age group was 21-40 years. The male: female ratio was 2.7:1. Fifty-one patients had isolated fingernail involvement, while involvement of toenails was seen in 15 patients. Distolateral subungual onychomycosis (67%) was the commonest clinical type followed in decreasing order by superficial white onychomycosis (14.6%), proximal subungual onychomycosis (9.8%), candidal onychomycosis (7.4%) and total dystrophic onychomycosis (1.2%). Trichophyton mentagrophytes (28.8%) was the most common pathogen isolated followed by Trichophyton rubrum (21.2%), Trichophyton tonsurans (11.5%), Candida albicans (11.5%), Trichospron beigelii, (9.6%), Epidermophyton floccosum (7.7%), Trichophyton violaceum (5.8%), and Aspergillus flavus (3.9%). Distolateral subungual onychomycosis was the most common clinical presentation and T. mentagrophytes and T. rubruni were the most frequently isolated fungi for onychomycosis in eastern Nepal.
