Abstract

Kerion celsi is an inflammatory infection, caused by a vigorous T-cell mediated host response to the dermatophyte infection. In the case of severe inflammation, it can be misdiagnosed as other disease like cellulitis, impetigo, furuncle and epidermal cyst. Microsporum(M.) canis is most likely transmitted by contact of animal hosts such as cats and dogs with humans. We report the 75-year-old female who presented two months history of tender erythematous scaly plaques with pustules, crusts on right scalp area. At first, from the histopathologic findings of the lesion, the patient was diagnosed epidermal cyst because of cyst-like structure in mid-dermis. But the fungal culture revealed M. canis as the causative fungus. Herein we report a educational case of kerion celsi mistaken for ruptured epidermal cyst.
