Evaluation of Tinea Cruris in the Patients Referred to Clinical Laboratory of Tabriz University of Medical Sciences

Background and Objectives:Dermatophytosis refers a group of infections that cause keratinised tissues such as skin, hair and nails. Infections caused by dermatophytes are named according to the anatomical location involved as tinea capitis, tinea corporis, tinea barbae, tinea cruris, tinea manuum, tinea pedis and tinea unguium. The aim of this study was to evaluate tinea cruris in patients referred to the clinical laboratory of Tabriz University of Medical Sciences (1998-2001). Materials and Methods: This study was performed on 2150 cases referred to mycology laboratory. 291 out of cases had lesions (positive samples) on crural folds. Skin scales were taken from suspected lesions. A portion of each clinical specimen was examined microscopically. The remaining portion of specimen was inoculated on mycologic media and results reported after 3 or 5 weeks. Results: The results indicated that 125 (42.9%) cases had tinea cruris caused by dermatophytes. 82 (28.2%) out of cases were male and 43 (14.7%) female. Other fungal agents such as candida 21 (7.2%) cases, malassezia 11 (3.8%) cases, bacterial agents such as corynebacterium minutissimum 82 (28.2%) cases were isolated. Conclusion: These findings suggest that epidermophyton floccosum with 93 (74.4%) cases is the most etiological agent of tinea cruris. Trichophyton mentagrophytes with 26 (20.8%) cases and irichophytone rubrum with 4 (3.2%) cases are the other agents responsible.
