The most common form, plaque psoriasis, appears as raised red lesions covered with a silvery film. It often occurs on the elbows, knees, and lower back, but can appear on any part of the body. The plaques may be itchy or painful. Psoriasis is a chronic condition that usually first strikes in the teen years, but 20,000 children in the . under age 10 will be diagnosed with psoriasis each year. Guttate psoriasis, another form that's more common in children, is usually triggered by a bacterial infection (often strep throat) and appears as smaller (up to 1 cm), scaly patches on the trunk, limbs and scalp. Though rare in babies, psoriasis is sometimes misdiagnosed as diaper rash or cradle cap.
Raynaud’s phenomenon is a condition in which the blood vessels in the hands and/or feet go into spasm, causing restricted blood flow. Lupus-related Raynaud’s usually results from inflammation of nerves or blood vessels and most often happens in cold temperatures, causing the tips of the fingers or toes to turn red, white, or blue. Pain, numbness, or tingling may also occur. People with Raynaud’s phenomenon should try to avoid cold conditions, and, if necessary, should wear gloves or mittens and thick socks when in an air-conditioned area.
