Guttate psoriasis

Guttate psoriasis is a relatively uncommon form of psoriasis. It is usually seen in patients younger than 30. The condition often develops very suddenly, usually after an infection, most notably strep throat. Guttate psoriasis is not contagious, which means it cannot spread to other people.

Psoriasis seems to be passed down through families. Doctors think it probably occurs when the body's immune system mistakes healthy cells for harmful substances. See: Inflammatory response

In addition to strep throat, the following may trigger an attack of guttate psoriasis:

• Bacteria or viral infections, including upper respiratory infections
• Injury to the skin, including cuts, burns, and insect bites
• Some medicines, including those used to treat malaria and certain heart conditions
• Stress
• Sunburn
• Too much alcohol

In general, psoriasis may be severe in persons who have a weakened immune system. This may include persons who have:

• AIDS
• Autoimmune disorders, including rheumatoid arthritis
• Chemotherapy for cancer
