Guttate psoriasis is a skin condition in which small, red, and scaly teardrop-shaped spots appear on the arms, legs, and middle of the body. It is a relatively uncommon form of psoriasis. The condition often develops very suddenly, and is usually triggered by an infection (e.g., strep throat, bacteria infection, upper respiratory infections or other viral infections). Other triggers include injury to the skin, including cuts, burns, and insect bites, certain malarial and heart medications, stress, sunburn, and excessive alcohol consumption.

The goal of treatment is to control the symptoms and prevent secondary infections.

Mild cases of guttate psoriasis are usually treated at home. The following may be recommended:

• Cortisone (anti-itch and anti-inflammatory) cream
• Dandruff shampoos (over-the-counter or prescription)
• Lotions that contain coal tar
• Moisturizers
• Prescription medicines containing vitamin D or vitamin A (retinoids)

People with very severe guttate psoriasis may take medicines to suppress the body's immune system. These medicines include corticosteroids, cyclosporine, and methotrexate.

Sunlight may help some symptoms go away. Care should be taken to avoid sunburn. Some people may choose to have phototherapy. Phototherapy is a medical procedure in which the skin is carefully exposed to ultraviolet light. Phototherapy may be given alone or after taking a drug that makes the skin more sensitive to light.
