Guttate Psoriasis (cont.)

What Are Guttate Psoriasis Symptoms and Signs?

  • Small, salmon-pink (or red) papules (bumps) usually appear suddenly on the skin two to three weeks after a streptococcal throat infection, or tonsillitis.
  • The drop-like lesions may itch.
  • The outbreak usually starts on the trunk, arms, or legs and sometimes spreads to the face, ears, or scalp. The palms and the bottoms of the feet are usually not affected.
  • Nail changes, such as pits and ridges, which are characteristic of chronic psoriasis, may be absent.

How Do Health-Care Professionals Diagnose Guttate Psoriasis?

Guttate psoriasis is typically diagnosed after a doctor or health-care professional performs a physical exam of the skin. The dermatologist (skin doctor) generally can tell if it is psoriasis just by clinical judgment based on the appearance of the skin lesions. Skin biopsies are occasionally necessary to confirm diagnosis. Blood tests to rule out other treatable diseases may be necessary.

Findings from blood tests may confirm that the patient had a streptococcal infection recently. Increased levels of antibodies to the streptolysin-O are present in more than one-half of patients.
