Guttate Psoriasis

Guttate psoriasis looks like small, salmon-pink (or red) drops on the skin. The word guttate is derived from the Latin word gutta, meaning drop. Usually, a fine scale is on the droplike lesion that is much finer than the scales in plaque psoriasis. Guttate psoriasis usually occurs on the trunk, arms, or legs. However, it may cover a large portion of the body. This type of psoriasis often “runs its course” and may even go away without treatment in a few weeks. Many cases are more persistent and require treatment.

The guttate form of psoriasis is the second most common form of psoriasis. About 2% of those with psoriasis have the guttate type. This type of psoriasis is more common in children and adults younger than 30 years.

The trigger to the disease is usually a streptococcal (bacterial) infection. The eruption of the lesions on the skin usually occurs at 2-3 weeks after the person has strep throat. The outbreak can go away and not return. Outbreaks may also go away but return with repeated episodes of strep throat, particularly if the person is a strep carrier (always carries streptococcal bacteria in his respiratory system).
