Chapter 4: Papulosquamous Disorders

Lichen Striatus

What is it?

Lichen striatus is a transient linear rash that is seen in school age children. The cause is unknown, but it is seen more commonly in girls than boys.

What does it look like?

Lichen striatus presents with a linear band of erythematous papules with slight scale. It is commonly seen presenting in a stripe down and arm or leg, but can be seen on the face or trunk. Over time, the lesions fade and often leave hypo- or hyper-pigmentation that resolves slowly over months.

How is it treated?

No treatment is necessary, and families can be reassured. For some children, there is associated pruritus and mid-potency topical steroids might be helpful.
