Overview
Guttate psoriasis is a type of psoriasis that creates small, red, scaly patches on your skin. The word "guttate" comes from the Latin word for "drop," which describes how these patches look. They're usually about the size of a water drop or smaller.
This condition most often affects children and young adults under 30. It can appear suddenly, covering your torso, arms, legs, and sometimes your face and scalp. Unlike other forms of psoriasis, guttate psoriasis often develops after an infection, particularly strep throat.
About 10% of people with psoriasis have the guttate type. While it can be alarming when it first appears, many cases improve on their own. However, some people may develop chronic plaque psoriasis later in life.
Symptoms & Signs
Guttate psoriasis symptoms can appear quickly, sometimes within days of an infection. The patches are usually smaller and thinner than those seen in other types of psoriasis.
Primary Symptoms
Small, drop-shaped red or pink patches covered with fine scales
Patches that appear suddenly across the torso, arms, and legs
Mild to moderate itching or burning sensation
Patches that may cover large areas of the body at once
When to Seek Care
You should contact a healthcare provider if you develop widespread red patches on your skin, especially after being sick. If patches become infected or you develop fever, seek care immediately.
When to Seek Immediate Care
Get emergency help if you have signs of infection like pus, red streaks, or fever above 101°F along with your skin symptoms.
Causes & Risk Factors
Age
Most common in children and adults under 30 years old
Genetics
Family history of psoriasis increases risk significantly
Lifestyle
Smoking, excessive alcohol use, and high stress levels
Other Conditions
Recent strep throat, respiratory infections, or HIV
Diagnosis
Medical History & Physical Examination
Your doctor will examine your skin carefully and ask about recent illnesses, especially sore throats or respiratory infections. They'll look at the size, shape, and location of the patches. The doctor will also ask about your family history of psoriasis and any medications you're taking.
Diagnostic Testing
Throat culture or rapid strep test to check for strep bacteria
Skin biopsy if the diagnosis is unclear or patches look unusual
Blood tests to rule out other conditions that cause similar rashes
Treatment Options
Treatment for guttate psoriasis focuses on reducing inflammation and helping your skin heal. Many mild cases improve without treatment as the triggering infection clears up.
Conservative Treatments
Topical corticosteroids to reduce inflammation and itching
Moisturizers and emollients to keep skin soft and prevent cracking
Coal tar preparations to slow skin cell growth and reduce scaling
Advanced Treatments
Phototherapy (UV light treatment) for widespread cases that don't respond to topical treatments
Oral medications like methotrexate for severe cases that cover large body areas
Biologic medications for people who don't respond to other treatments
Living with the Condition
Daily Management Strategies
Keep your skin moisturized with gentle, fragrance-free lotions applied several times daily. Take lukewarm baths or showers and avoid harsh soaps that can irritate your skin. Pat skin dry gently instead of rubbing. Wear loose, soft clothing that won't rub against affected areas.
Exercise & Movement
Regular exercise can help reduce stress, which may improve your symptoms. Choose activities that don't cause excessive sweating or skin friction. Swimming in chlorinated pools should be followed by immediate showering and moisturizing. Avoid contact sports that might injure your skin while you have active patches.
Prevention
Treat strep throat and other bacterial infections promptly with antibiotics
Practice good hygiene to prevent respiratory and throat infections
Manage stress through relaxation techniques, exercise, or counseling
Avoid known triggers like certain medications or excessive sun exposure
Keep your skin moisturized to maintain a healthy skin barrier
Don't smoke and limit alcohol consumption as both can worsen psoriasis
Frequently Asked Questions
No, guttate psoriasis is not contagious. You cannot catch it from someone else or spread it to others. While it may develop after an infection like strep throat, the psoriasis itself is an immune system response, not an infection.

Yes, guttate psoriasis commonly affects children and teenagers. It often develops after strep throat infections in kids. While it can look alarming, most childhood cases clear up on their own with proper care and treatment of any underlying infections.
About one-third of people with guttate psoriasis may later develop chronic plaque psoriasis. However, many people have only one episode that clears completely. Your risk may be higher if you have a family history of psoriasis or multiple episodes.
