Psoriasis: Guttate
Guttate psoriasis is identifiable by small, red, drop-shaped spots that are widespread on the trunk and limbs. Guttate lesions have thinner scales and are flatter than the thickened plaques of other types of psoriasis. It starts most commonly in children or adolescents.
Like all forms of psoriasis, guttate psoriasis is the result of overly rapid skin cell growth that leads to scaly, itchy lesions called plaques. In the case of guttate psoriasis, there is often a trigger, most commonly an infection with streptococcus (strep), the bacteria that causes strep throat. Strep can cause a flare-up even without causing a sore throat or other symptoms. Identifying and treating a suspected infection are important steps toward eliminating guttate psoriasis outbreaks.
Although mild cases of guttate psoriasis can go away on their own, most people need some treatment. Guttate lesions usually respond well to topical medications, but it can be difficult to apply the medicine to each of the widely scattered spots. Fortunately, guttate psoriasis also responds well to natural sunlight or phototherapy, so these are frequently used as a first-line treatment.
It is only occasionally necessary to use systemic treatments such as cyclosporine, methotrexate, or oral retinoids (Soriatane).
People who are susceptible to strep infections and endure multiple guttate psoriasis outbreaks may consider preventive doses of antibiotics to avoid a recurrence.
