Abstract

This study aims to investigate the recent clinical and mycological trends of dermatophytoses in Pusan area. The number of patients with dermatophytoses diagnosed by KOH examination and culture at Maryknoll Hospital was 1, 213 during past 2 years from November 1982 to October 1984. The incidence rate of dermatopbytoses was 9. 8% out of 12,377 cases of out patients in total. Tinea pedis (33 .7%,) was the most frequent diagnosis, followed by tinea cruris, tinea unguium, tinea corporis, tinea faciale, tinea manus and tinea capitis, in the order of decreasing frequency. The majority of cases were found in the age group from 20 to 39 4, The over all ratio of male to female patients was ] 2: 1 5 The positive rate in KOH examination was 96. 2A, and it was especially low in the areas of scalp, face and toe webs. The positive culture rate was 55, 9g, and it was higher in the covered area than in the exposed area. 6 678 strains out of the 1, 213 patients were isolated and identified. The species isolated were, in the order of decreasing frequency, Trichophyton rubrum (558 strains, 82.3% of total organisms isolated), Tn'chophyton mentagrophytes (55,8, 1 Microsporum canis (48, 7. 1g) Epidermophyton floccosum (12, 1 8g) and Microsporum gypseum (5, 0. 7gp) Trichophyton rubrum was the major causative organism in all the types of dermatophytoses except tinea capitis and tinea faciale. In tinea capitis, Microsporum canis was the main causative organism, and Trichophyton ferrugineum was not isolated, at all, which was a specific point, compared with the past tendency. In tinea faciale, zoophilic organisms were mainly isolated.
