Eczema and dermatitis are used interchangeably to describe a variety of skin problems. The degrees of physical appearance and symptoms, as well as the locations of flare-ups, can depend on the type of dermatitis a person has. The most common signs of eczema or dermatitis are itchy and dry skin. The skin can become red, inflamed and scaly, and in extreme cases it can break open and bleed. Some forms of this skin disease can also cause small to large blisters or lesions to appear on the skin.

Eczema can affect people of all ages and backgrounds. Some forms are more common for women, and others for men or infants. The disease is not contagious, and some types are believed to be hereditary. There are many contributors to flare-ups, and people who experience the disease sometimes have severe allergies.

Atopic eczema is believed to be based on genetic makeup, meaning that it may be hereditary. The immune system may be extremely sensitive, and allergic reactions are shown by inflammation and rashes on the skin. Other types of dermatitis can be caused by reactions to chemicals and harsh elements in the environment.

Other Forms of Eczema
The varicose form affects the legs and is caused by poor blood circulation. The ankles and knee areas can become very itchy and inflamed, and sometimes speckled discoloration or blisters can appear on the skin. Discoid eczema produces red coin-shaped blisters on the skin, usually on the torso and sometimes on the legs.
