RESUMEN
Trichophyton(T.) verrucosum had not been reported until now in Korea. We report herein a case of kerion celsi caused by T. verrucosum considered the first case in Korea and its epidemiologic enviroment. She was a 10 years old girl living in cattle country. Three weeks ago, three small erythematous nodules were developed and rapidly progressed to be large boggy mass like tumefactions. Histopathologically, fungal hyphae and spores were found in hair follicles in H & E and PAS stain. In fungal study, characteristic features of T. verrucosum were found as chains of chlamidospores et als. With above results, we could diagnose these lesions as kerion celsi caused by T. verrucosum which were transmitted from a cattle. After 4 weeks-administration of ketoconazole, lesions were healed completely.
