Lichen striatus is a skin disease that presents with the sudden appearance of many small bumps typically in a line along an arm or leg.[3] It is seen primarily in children, most frequently appearing ages 5–15.[3]

The cause is not known, but possibly due to movement of a clone of abnormal cells along Blaschko's lines during fatal development.[4]

It s common.[3] It tends to occur more frequently in females, children and teens.[4]

Symptoms and signs

Lichen striatus impacts the skin and nails. It is seen as an unbroken or disrupted, linear band consisting of small tan, pink or flesh colored papules.

The papules could be smooth, flat topped or scaly. The band of lichen striatus varies from a few millimeters to 1-- 2 cm wide and extends from a few centimeters to the complete length of the extremity. By and large, the papules are unilateral and single on an extremity along the lines of Blaschko.

Itching is an accompanying function of the disorder.


Diagnosis is based on observing the appearance of the lesions.[5]
