Could It be Wolf Isotopic Response?: Occurrence of Dermatophytoses on Vitiliginous Skin-Case Series of Five Cases from a Tertiary Care Centre in India.

Wolf isotopic response is the occurrence of new dermatoses on areas of the skin with previous but still active dermatoses. Vitiligo is an acquired disorder characterized by the loss of functional melanocytes which manifests as circumscribed depigmented macules and patches. Dermatophytoses are superficial fungal infections caused by three genera of fungi (Microsporum, Trichophyton, and Epidermophyton) that have the unique ability to invade and multiply within keratinized tissue (skin, hair, and nail). The appearance of dermatophyte infection on previously present vitiligo lesion is an uncommon example of Wolf response. We describe a case series of five vitiligo patients that presented to our OPD over 1 year period.
