Guttate [GUH-tate] psoriasis appears as small, round spots called papules [PAP-yules] that are raised and sometimes scaly. Papules are caused by inflammation in the skin and often appear on the arms, legs, and torso. However, you may develop papules on your face, ears, and scalp.
Guttate psoriasis often develops suddenly. It may start after an infection such as strep throat. Strep throat is caused by an infection of streptococcal [strehp-tuh-KAH-kuhl] bacteria. It is possible to have strep throat without symptoms. Speak with your health care provider about testing for strep throat if you develop guttate psoriasis.
Other common triggers include:
- Certain medicines, such as antimalarials and beta blockers
- Infections such as the flu, sinus infections, or upper respiratory infections
- Streptococcal infection
- Tonsillitis (inflammation of the tonsils)
- Injury to the skin
