Clinical and Mycologic Studies of Tinea Cruris
Abstract
-
BACKGROUND: The incidence and causative dermatophytes of tinea cruris has been changed with time. Although clinical and mycologic studies of whole dermatophytosis have been reported many times, there have been only a few studies about tinea cruris reported.
OBJECTIVE
The purpose of this study was to investigate clinical and mycological features of tinea cruuis.
METHODS
We evaluated the clinical and mycologic aspects of tinea cruris in 598 patients with tinea cruris from January 1985 to December 1997 in Yeungnam University Hospital.
RESULTS
The incidence of tinea cruris was 20.8% of 2,878 total dermatophytoses. The ratio of male to female patients was 23.9:1. And most of them were in their twenties and thirties. Most(82.1%) of them involved both sites of the groin. Concurrent dermatophytic infections of tinea cruris were noted in 29.4% of the cases and the most common one was tinea pedis(22.4%). Three hundred and thirty eight dermatophytes were isolated from 598 patients with tinea cruris. They were Trichophyton(T.) rubrum(95.3%), T. mentagrophytes(4.4%), Epidermophyton floccosum(1.2%), Microsporum canis(0.9%).
CONCLUSION
Tinea cruris is a male predominant dermatophytosis, the most common causative organism is T. rubrum, and tinea pedis seems to be an important reservoir.
