Abstract

Wolf's isotopic response refers to the occurrence of a new skin disease at the exact site of an unrelated skin disease that had previously healed. Herein we report a case of wolf’s isotopic response cutaneous lichen planus following psoriasic lesion, that has not been reported before. The initial skin disease was psoriasis and the isotopic response was a lichenoid reaction (lichen planus).
