Abstract
Background: Trichophyton verrucosum (T. verrucosum) is a zoophilic dermatophyte distributed all around the world. In Korea, kerion celsi caused by T. verrucosum was first reported by Kim et al in the southeast province of Korea. Since then, many patients infected with T. verrucosum have been reported in Young-nam, Chungcheong province, and so on.
Objective: There have been few reports on the T. verrucosum in Korea, yet. Authors tried to offer the information on dermatophytosis due to T. verrucosum in the various aspects such as prevalence of each year, epidemiology, onset time of the year and season, distribution and characteristics of the regions, sex and age distribution, the clinical types, onset site of the body, and the relation between human beings and infected cattle and so on.
Method: A total of 218 patients who visited Catholic Dermatologic Clinic in Daegu, Korea from 1986 to 2004, were finally diagnosed as T. verrucosum infection by KOH and fungal culture. The data were based on a retrospective survey of hospital records. However, whenever the information was lacking, we called patients to ask lists of questions for the investigation.
Results: The number of patients had increased every year since the first report in 1986. In 1988, the number was up to 44, which was the most. After the year 2000, the number of patients had been decreasing so continuously that there was no case in the year 2003 and 2004. As we see the distribution of province, 47 cases were from Daegu, 137 cases from Kyungsang bukdo, 29 cases from Kyungsang namdo, 5 cases from other provinces and cyties. In the distribution of season, 81 cases appeared in the spring, which was the most. Female to male ratio showed about a 1.2-fold predominance for male. And less than 15-year-old group was 41.3% of total patients. The most frequent onset site was face (36 cases, 16.5%), and the next were arm, trunk, head, leg, neck in the decreasing orders. Classifying the patients by the clinical type, 150 cases (68.8%) were in the tinea circinata type, and the next were kerion celsi type, tinea barbae type, agminated folliculitis type in the decreasing orders. Among 126 cases, 99 patients raised cattle with lesions caused by T. verrucosum, 8 patients raise cattle without lesions, 19 patients didn't breed cattle.
Conclusion: This investigation is expected to help understand and obtain more information on T. verrucosum infection in Korea.
