Abstract

Lichen striatus is a self-limited lichenoid eruption that follows Blaschko’s lines. It is particularly common in children and rarely seen in adults. Cases related to atopic diathesis are common, besides it is reported among family members. Viral infections, vaccines and trauma related cases are also present. Various environmental stimuli in the setting of genetic predisposition may play a role. We herein, reported a forty eight year-old woman who developed lichen striatus eruptions in her arm and trunk while she was receiving UVB treatment with maintenance dose for psoriasis. Phototherapy might act as a stimulant with its immunosuppressive and traumatic effects.
