Background: Trichophyton (T.) mentagrophytes is the second common dermatophyte in Korea. But there were rare reports on epidemiological and mycological analysis of T. mentagrophytes with long term and large scale study in Korea. Objectives: The aim of this study is to explain epidemiological and mycological characteristics of T. mentagrophytes in Korea. Methods: During the 21-year-period from 1992 to 2012, 6,250 patients with T. mentagrophytes were surveyed with respect to annual incidence, the distribution of the subjects according to age, sex, season, involved sites and a place of residence. Patients with T. mentagrophytes infection were clarified with fungal culture. In addition, we classified the colony appearance of T. mentagrophytes into granular, persicolor, powdery and downy colony. Results: In an epidemiological analysis, annual incidence reached its peak in 2005, and then gradually decreased. T. mentagrophytes was most common in July at monthly distribution. It was also found predominantly in middle-aged adults, especially in forties in age. In a mycological analysis, powdery colony was most common, followed by persicolor and granular colony. Clinically, tinea pedis was the most common T. mentagrophytes infection, followed by tinea unguium and tinea facieii. Conclusion: This massive, long term study on T. mentagrophytes infection leads us into epidemiological and mycological information in Korea.
