Objectives:

Cutaneous fungal infections are among the relatively common mycoses, comprising a considerable percentage of admissions to physicians, especially dermatologists. Knowing the frequency, distribution, and geographic status of these diseases can be helpful for planning for control and prevention of them by the health system managers. The objective of this descriptive, retrospective study was to determine the relative frequencies of various fungal diseases in persons admitted to Yazd central laboratory.

Methods:

From autumn of 2000 to spring of 2003. Sampling had been performed from the patients referred to this laboratory by the physicians. After clearing the specimen in 10–20% KOH and lactophenol, microscopic exam of direct smears, and if requested by the physician, culture on Sabouraud's dextrose agar and Mycosel agar (SC and SCC) had been done, and the results were written in laboratory work lists. The demographic data and results of tests on 3744 such cases were evaluated and analysed by SPSS Win software.

Results:

From total 3744 cases, 1508 cases (40%) were positive for superficial and cutaneous fungal agents, including 855 males and 653 females. There was a statistical significant (P = 0.000) difference between 2 sexes regarding the relative frequencies of infections. Dermatophytes (43.6%) and malassezia furfur (33.4%) were the most common offenders, and erythrasma, candidiasis, other yeasts, and saprophytes comprised other infections in decreasing order of frequencies (P = 0.001). The most commonly afflicted age groups were 20–29 years (26.7%) and 10–19 years (26%). The least commonly infected persons belonged to 60 years and more age group. Upper extremities (17.8%) and axilla (1.6%) were the most and least commonly infected areas, respectively. Only 169 cases (17%) of 966 requested cultures were positive, and the zoophilic fungus Trichophyton verrucosum (26.6%) was the most frequently isolated organism. Trichophyton schoenleinii (1.2%) had the least frequency.

Conclusion:

It seems that tinea versicolor and the contagious dermatophytosis with zoophilic agents have higher prevalence in this area and more education and health care programmes are needed.
