BACKGROUND: The skin lesion of dermatophytosis is best shown in the lesion of tines corporis. The most common one is an annular lesion with central clearing area. But its size and features are various according to the dermatophytes.
OBJECTIVE
The purpose of this study is to evaluate the correlation of clinical and mycological features of tinea corporis.
METHODS
The clinical features of 113 patients with tinea corporis from February to April 1998 in Catholic Skin Disease Clinic were evaluated. KOH examination and culture from the lesion were done. And dermatophytes were identified with colony morphology and microscopic findings.
RESULTS
The ratio of male to female was about 1.7:1 and showed more prevalence in male. Patients with tinea corporis were the most common in the thirties. Of all 113 patients with tinea corporis, single lesion (75 cases, 66.4%) was the most common. In the size of individual lesion, 40 cases (35.4%) were larger than 10cm. The unexposed area (66.0%) was more frequently affected than exposed area (34.0%) and the most common site was buttock (32.1%). Twenty-eight cases (24.8%) had a history of contact with animals and men that were thought be to infection source. Coexisting dermatophytoses in patients with tinea corporis were noted in 66 cases that had 104 lesions of other dermatophytosis. And they were tinea pedis (34.6%), tinea unguium (33.7%), tinea cruris (15.4%) and tithe.5. From 113 patients with tinea corporis, 77 dermatophytes were isolated. They were composed of Trichophyton(T.) rubrum(67cases), T. mentagrophytes(7 cases) and Microsporum(M.) canis(3cases). In 67 cases with T. rubrum infection, 64 cases had annular type, 48 cases had single lesion and 29 cases had larger than loom in size of lesion. In 7 cases with T. mentagrophytes infection, 6 cases had annular type, 6 cases had one lesion and size of lesion was variable. In 3 cases with M. canis infection, all cases had annular type, 2 cases had single lesion and 2 cases had lesions smaller than 2cm in size.
CONCLUSION
There findings suggest that clinical features were characteristic according to its causative dermatophytes.
