About 80% of people with psoriasis have this type. It causes plaques, which are raised, red or purple patches of skin with silvery-white scales. These plaques can appear anywhere, but usually affect elbows, knees, scalp and lower back.

This type develops in skin folds or creases, such as your armpits, groin or under the breasts. It usually appears as smooth, red patches that may be painful or itchy.

This type causes small, teardrop-shaped spots that often appear on your trunk and limbs. It frequently develops in children and young adults, sometimes following a strep throat infection or other illness.

This more severe form causes red patches with small, pus-filled bumps. Pustular psoriasis often affects the palms of your hands and soles of your feet.

This rare and severe type can cause painful or itchy discoloration across your body. This condition can cause severe complications, including heart rate changes and dehydration, that require hospitalization.

Your dermatologist will examine your skin, scalp and nails, looking for signs of psoriasis. They will also ask you about your personal and family health history.

Your doctor may recommend a biopsy if the diagnosis is unclear based on appearance alone. This involves taking a small sample of your skin and examining it under a microscope.

For mild to moderate psoriasis, medications applied directly to the skin are often the first line of treatment. These medications may include creams and ointments that fight inflammation, slow down skin cell growth and relieve scaling and itching.

Medical light therapy uses ultraviolet (UV) light to slow skin cell growth and lower inflammation. These therapies are different from tanning beds because they directly target the psoriasis in a controlled way.

If topical treatments do not provide enough relief, your doctor may recommend systemic medications, such as pills or injections/infusions. These medications may help calm the immune response, reduce inflammation or slow down skin cell production.
