This study was undertaken to document the clinico-mycological pattern of onychomycosis in Iran. Both the direct microscopy and the cultures of the nail material were performed over a 4-year period to identify the causative agents. The microscopic and/or cultural detection of fungi (dermatophytes, yeasts and saprophytic moulds) were positive in 40.2% of samples. The most common clinical type noted was distolateral subungual onychomycosis (48.4%). Etiological fungal agents were 50% dermatophytes, 46.8% yeasts, and 3.2% saprophytic moulds. The most frequently detected fungi were Trichophyton rubrum and Candida albicans. Aspergillus niger and A. flavus were the most frequent saprophytic moulds. Females affected more frequently than males and in both sexes, those who were 40-49 years old, more infected. Fingernails were affected more frequently than toenails. The clinico-epidemiological data collected would serve as reference for future research and may be useful in the development of preventive and educational strategies.
