Guttate psoriasis is a type of psoriasis that looks like small, salmon-pink drops on the skin. The word guttate is derived from the Latin word gutta, meaning drop. Usually there is a fine scale on the drop-like lesion that is much finer than the scales in plaque psoriasis, which is the most common type of psoriasis.

Guttate psoriasis is not contagious and usually occurs on the trunk, arms, or legs. However, it may cover a large portion of the body.

The trigger of the disease is usually a streptococcal (bacterial) infection. The eruption of the skin lesions usually happens about two to three weeks after a person has strep throat. The outbreak can go away and not recur. Outbreaks may also go away and come back, particularly if the person is a strep carrier (carries streptococcal bacteria in his respiratory system).

The sudden appearance of an outbreak may be the first psoriasis outbreak for some people. Alternatively, a person who has had plaque psoriasis for a long time may suddenly have an episode of guttate psoriasis. This type of psoriasis can also be chronic and can be triggered by infections other than those from streptococcal bacteria. For example, the chicken pox or colds can trigger the psoriasis.

Who gets guttate psoriasis?

The guttate form of psoriasis is relatively uncommon. Fewer than 2% of those with psoriasis have the guttate type. Guttate psoriasis is more common in children and adults younger than 30 years. Boys and girls are equally affected.
