Congenital ichthyosis associated with Trichophyton rubrum tinea, imitating drug hypersensitivity reaction.

Tinea corporis and congenital ichthyoses are common dermatological diseases. The association of the two disorders is plausible due to the immunological and barrier defects of ichthyoses; however, relatively limited literature is available in this field. Since superficial fungal infections possess atypical morphology in keratinization disorders, and could imitate other dermatological conditions, the correct diagnosis can be challenging. We present the case of a 54-year-old woman with ichthyosis, who was initially treated for drug-hypersensitivity reaction.
