Abstract

Microsporum(M.) gypseum, a geophilic dermatophyte, causes dermatophytosis that is characterized by rapid development and resolution. M. gypseum infection is rare due to its low infectivity, and there have been no previous case reports of infection with this dermatophyte after scratch injury by a dog. Here, we report a case of annular, scaly, erythematous plaques on the right ankle of a 5-year-old female patient after being scratched on the leg by a dog. Histopathological examination showed fungal hyphae on the stratum corneum. M. gypseum was identified by tissue culture and polymerase chain reaction. She was treated with sertaconazole cream. In this case, M. gypseum may have been transferred to the scratched area from contaminated soil or from the claws of the dog.
