Lichen planus (LP) is a common skin disease characterized by tiny, polygonal, flat-topped, pink to violaceous papules, sometimes surmounted by Wickham’s striae. We report a case of LP localized at the same site of an already healed herpes zoster. This variant is defined zosteriform LP and is a classic example of Wolf’s isotopic response. Zosteriform lichen planus should be distinguished from linear LP, that may be due to koebnerization or may follow Blaschko lines, and other linear dermatoses. Zosteriform LP may be explained by the hypothesis of the immunocompromised district.
