Lichen striatus is a rare skin condition that is seen primarily in children, most frequently appearing ages 5–15.
[3]: 226–27 It consists of a self-limiting eruption of small, scaly papules.
It is seen as an unbroken or disrupted, linear band consisting of small tan, pink or flesh colored papules.
The band of lichen striatus varies from a few millimeters to 1-2cm wide and extends from a few centimeters to the complete length of the extremity.
By and large, the papules are unilateral and appear on extremities along the lines of Blaschko.
