Pityriasis lichenoides is a skin disorder of unknown cause.  There are two types of pityriasis lichenoides; a more severe form with a sudden onset that tends to be short-lived (acute) which is usually found in children, known as pityriasis lichenoides et varioliformis acuta and a more mild but long-lasting (chronic) form known as pityriasis lichenoides chronica.[1] Pityriasis lichenoides chronica may clear up in a few weeks or persist for years.[1]
