Eczema is a term for a group of medical conditions that cause the skin to become inflamed or irritated. The most common type of eczema is known as atopic dermatitis, or atopic eczema. Atopic refers to a group of diseases with an often inherited tendency to develop other allergic conditions, such as asthma and hay fever.
Eczema affects about 10% to 20% of infants and about 3% of adults and children in the U.S. Most infants who develop the condition outgrow it by their tenth birthday, while some people continue to have symptoms on and off throughout life. With proper treatment, the disease often can be controlled.
What Are the Symptoms of Eczema?
No matter which part of the skin is affected, eczema is almost always itchy. Sometimes the itching will start before the rash appears, but when it does, the rash most commonly appears on the face, back of the knees, wrists, hands, or feet. It may also affect other areas as well.
Affected areas usually appear very dry, thickened, or scaly. In fair-skinned people, these areas may initially appear reddish and then turn brown. Among darker-skinned people, eczema can affect pigmentation, making the affected area lighter or darker.
Psoriasis can't be passed from person to person. It does sometimes happen in members of the same family.
It usually appears in early adulthood. For most people, it affects just a few areas. In severe cases, it can cover large parts of the body. The rashes can heal and then come back throughout a person's life.
Psoriasis starts as small, red bumps, which grow bigger and form scales. The skin appears thick but may bleed easily if you pick or rub off the scales.
Rashes may itch and skin may become cracked and painful . Nails may form pits, thicken, crack and become loose.
What Is Acne?
There's a reason it's called "common acne" -- nearly everyone suffers from a pimple outbreak at some point in life.
It starts when greasy secretions from the skin's sebaceous glands (oil glands) plug the tiny openings for hair follicles (plugged pores). If the openings are large, the clogs take the form of blackheads: small, flat spots with dark centers. If the openings stay small, the clogs take the form of whiteheads: small, flesh-colored bumps. Both types of plugged pores can develop into swollen, tender inflammations or pimples or deeper lumps or nodules. Nodules associated with severe cases of acne (cystic acne) are firm swellings below the skin's surface that become inflamed, tender, and sometimes infected.
Although acne remains largely a curse of adolescence, about 20% of all cases occur in adults. Acne commonly starts during puberty between the ages of 10 and 13 and tends to be worse in people with oily skin. Teenage acne usually lasts for five to 10 years, normally going away during the early 20s. It occurs in both sexes, although teenage boys tend to have the most severe cases. Women are more likely than men to have mild to moderate forms into their 30s and beyond.
