Tinea capitis (48 cases, 31.8%) was the most frequent dermatomycosis diagnosed. It was more prevalent in children in the age group of 1-10 years. Trichophyton violaceum and Microsporum canis were the most frequent dermatophytes isolated as the etiologic agent. The second most common and frequent dermatomycosis was tinea corporis (45 cases, 23.3.%). The most prevalent etiologic agents were Trichophyton violaceum, Microsporum canis, M. audouinii and T.rubrum.
