What Is Guttate Psoriasis?
Guttate psoriasis is a type of psoriasis that shows up on your skin as red, scaly, small, teardrop-shaped spots. It doesn’t normally leave a scar. You usually get it as a child or young adult. Up to 10% of people with psoriasis have this type. It’s not as common as plaque psoriasis.
It’s an autoimmune disease, meaning your body treats your own cells like invaders and attacks them. You might get it only once, or you could have several flare-ups. In some cases, this type of psoriasis doesn’t go away. With the help of your doctor, you can find a treatment to keep your symptoms under control.
An outbreak is usually triggered by a bacterial infection — typically streptococcus (strep throat). It sets off an immune system reaction that causes the spots on your skin.
In some cases, guttate psoriasis is genetic. If someone in your family has it, your chances of getting it go up.
