Abstract

Isotopic response describes the occurrence of a new skin disorder at the site of another one, already healed and unrelated. The preceding diseases are mostly herpes zosters. Reactive perforating collagenosis is rare dermatosis that has characteristic histopathologic features; transepidermal elimination of degenerated dermal collagen fibers. There has been only one report of an reactive perforating collagenosis occurring on the healed site of herpes zoster. We present a case of acquired reactive perforating collagenosis that was developed on the site previously affected by herpes zoster in a 67-year-old woman, which is thought to be an isotopic response.
