Guttate psoriasis

Guttate psoriasis is most common in children and young adults. It often starts after an infection, such as strep throat. This type of psoriasis causes small, drop-shaped spots on the trunk, arms or legs. The spots are covered with flaky, silver scales and may look red, purple, gray or brown, depending on your skin color. They also can be itchy.

Treatment often includes light therapy, prescription steroid cream, or other creams that contain vitamin D. If you have more serious symptoms, you may need prescription medicines taken by mouth or given as a shot. If you have an infection, your healthcare professional may prescribe an antibiotic medicine to treat it.
