Outlook

• Although guttate psoriasis usually clears up within a few weeks, it may also be the first step to chronic plaque psoriasis.

• The acute guttate form progresses into the chronic plaque form in an estimated 68% of people.

• In another study of 15 patients, the likelihood of an individual developing chronic psoriasis within 10 years of a single episode of acute guttate psoriasis was suggested to be about 1 in 3. Although further studies with larger numbers of patients are needed to determine the risk more accurately.

• Like other forms of psoriasis, guttate psoriasis has the tendency to improve during the summer and worsen during the winter. Once the outbreak clears, many patients with acute guttate psoriasis usually have limited or no evidence of psoriasis for prolonged periods.
