Guttate psoriasis is more common in children and young adults and is usually triggered by a bacterial infection such as strep throat. It's marked by small, reddish sores, mainly on the trunk, arms and legs. The sores are covered by a fine scale and aren't as thick as typical plaques are. You may have a single outbreak that goes away on its own, or you may have repeated episodes.
Guttate psoriasis typically responds to treatment, which includes light therapy, prescription steroid creams and oral medications. It may also improve with treatment of the underlying cause or infection, if identified.
