Summary
Objective

Dermatomycoses are considered as an important group of fungal diseases with worldwide distribution. This study was performed to analyze the spectrum of dermatomycoses in Tehran during a 4-year period from 2006 to 2009.

Patients and methods

A total of 12461 patients were investigated for mycoses. Of these, 4871 cases were positive. Plucked hairs, skin and nail scraping were examined and identified by direct microscopy and culture.

Results

From 4871 patients, 4015 strains were identified including dermatophytes (2635 cases, 65.7%), yeasts (1210 cases, 30.1%) and molds (170 cases, 4.2%). Among the dermatophytes, the most common pathogen isolated was Trichophyton rubrum (28.7%), followed by Epidermophyton floccosum (25.0%), Trichophyton mentagrophytes (23.8%) and Trichophyton tonsurans (11.5%). Among the yeast-like fungi, a predominance of Candida spp. (54.5%) was observed. Of these, 29.3% were C. albicans . Aspergillus spp. was the most prevalent isolated mold (71.8%).

Conclusion

Our results have demonstrated epidemiologic trends of dermatomycoses and their causative agents in recent years in comparison with the past records in Tehran and other parts of the world. This noticeable information can help to develop fungal diagnosis as well as more effective therapeutic methods.

Résumé
Objectif

Les dermatomycoses sont considérées comme un groupe important de maladies fongiques avec une distribution mondiale. L’étude a été réalisée afin d’évaluer l’importance des dermatomycoses à Téhéran pendant une période de quatre ans allant de 2006 à 2009.

Patients et méthodes

Un total de 12461 patients porteurs d’épidermomycose a été étudié. Parmi eux, 4871 cas ont été positifs. Les prélèvements de cuir chevelu, de peau et d’ongles ont été soumis à un examen microscopique direct et mis en culture.

Résultats

À partir de 4871 patients, 4015 souches ont été identifiées dont des dermatophytes (2635 cas, 65,7 %), des levures (1210 cas, 30,1 %) et des moisissures (170 cas, 4,2 %). Parmi les dermatophytes, le pathogène le plus souvent isolé était Trichophyton rubrum (28,7 %), suivi par Epidermophyton floccosum (25,0 %), Trichophyton mentagrophytes (23,8 %) et Trichophyton tonsurans (11,5 %). Parmi les champignons de type levure, une prédominance de Candida sp. (54,5 %) a été observée, dont C.  albicans (29,3 %). Aspergillus sp. a été la moisissure isolée la plus répandue (71,8 %).

Conclusion

Nos résultats ont montré l’importance épidémiologique des dermatomycoses et de leurs agents responsables au cours de ces dernières années en comparaison avec les dossiers antérieurs à Téhéran et dans d’autres parties du monde. Cette information sensible peut aider à développer le diagnostic fongique ainsi que des méthodes thérapeutiques plus efficaces.
