Guttate Psoriasis
Guttate
[GUH-tate] psoriasis is a form of psoriasis that often starts in childhood or
young adulthood. This is the second most common type of psoriasis, after plaque
psoriasis.
Symptoms
This
form of psoriasis appears as small, red, separate spots on the skin. Guttate
lesions usually appear on the trunk and limbs and can number in the hundreds.
Sometimes lesions form on the scalp, face and ears. They usually are not as
thick as the lesions that characterize plaque psoriasis. This form can precede
or co-exist with other forms of psoriasis, such as plaque.
Triggers
Guttate
psoriasis often comes on quite suddenly. There are a variety of known triggers,
including:
- Upper respiratory infections
- Streptococcal infections
- Tonsillitis
- Stress
- Injury to the skin
- Certain drugs (including
antimalarials and beta blockers)
A
streptococcal infection of the throat (strepthroat) is a common guttate
psoriasis trigger. You can have strep throat without symptoms. If you have a
flare of guttate psoriasis, talk with your health care provider about getting a
strep test to determine if you have an underlying strep infection.
Treatment
Treatment
Topicals are considered the preferred treatment
for guttate psoriasis. However, people often find it tedious to apply them to
the multiple small lesions on their skin. Phototherapy treatment with
ultraviolet light B (UVB) or PUVA (the light-sensitizing drug psoralen plus ultraviolet
light A) also is very effective for guttate psoriasis. Only in
severe cases will doctors prescribesystemic
medications (drugs
given orally or by injection) for this type of psoriasis. Sometimes, a short
course of one of these drugs results in rapid and prolonged clearing of guttate
psoriasis.
