Isotopic Phenomenon: Case Report and Distinctions Between the Isomorphic Phenomenon, Inverse Isomorphic Phenomenon and the Sign of Pathergy
Journal Title: Journal of Dermatology Research - Year 2025, Vol 6, Issue 1
Abstract
The isotope phenomenon, also called the Wolf’s isotopic response, refers to the emergence of a new skin disease at the exact location of a previously cured unrelated skin disease, often following infection with the herpes zoster virus. We report a case of isotopic phenomenon and provide brief comments on the distinctions between the isomorphic phenomenon, inverse isomorphic phenomenon and sign of pathergy.
