Guttate psoriasis is a skin condition in which small, red, scaly teardrop-shaped spots with a silvery scale appear on the arms, legs, and middle of the body. Guttate means "drop" in Latin.
Guttate psoriasis is a type of psoriasis. It is usually seen in persons younger than 30. The condition often develops suddenly. It usually appears after an infection, most notably strep throat caused by group A strep. Guttate psoriasis is not contagious. This means it cannot spread to other people.

Guttate psoriasis may clear completely following treatment. Sometimes, it may become a chronic (lifelong) condition, or worsen to the more common plaque-type psoriasis.
Untreated, this condition may result in:
