Hedgehogs have recently become popular exotic pets in Korea. Several diseases may be acquired from these animals including dermatophytosis, Salmonella infections, contact urticaria and possibly Mycobacterium infections. We describe here a 15-year-old girl who developed tinea manuum after keeping a hedgehog for 4 months. Diagnosis was confirmed by histopathologic and mycological examination. The causative agent was identified as Trichophyton mentagrophytes var. erinacei, a zoophilic dermatophyte.
