Childhood eczema is the most common and typically begins and shows up around 6 to 12 weeks of age. It first may appear around the cheeks and chin as a patchy facial rash which can progress to red, scaling, and oozing skin. Once the infant becomes mobile, and starts to crawl, exposed areas, such as the knees and elbows, amy get a rash because of crawling. Rash tends to begin with papules. Severe cases of atopic dermatitis may affect growth and the child may be shorter than average. Many infants get better by 18 months of age, although they remain at greater than normal risk for dry skin or hand dermatitis later in life, in adulthood. Although lots of people who had atopic as children also experience symptoms as adults, sometimes it first shows up in adulthood. It affects males and females equally and accounts for 10 to 20 percent of all referrals to dermatologists. The pattern in adults is similar to the one seen in children. Some adults are only affected on the hands or feet and have them dry, itchy, red and cracked. Adults with atopic also have a predisposition toward irritant contact dermatitis especially it exposed to chemicals. Sleep patterns and work performance may be affected.
