The exact causes of eczema are not known but it is believed that an abnormal function of the immune system could be a major factor. Some types of eczema could also be triggered by various substances like soap, jewelry, clothing and sweat. Environmental allergens may cause outbreaks of eczema as well as changes in temperature and stress can cause different types of eczema.

Atopic dermatitis or eczema is very commonly seen. The person will show signs of inflamed areas as well as these areas being itchy and is said to be caused by a malfunction of the body’s immune system. This type of eczema has cycles where it will disappear and then reappear and will also depend on what factors are causing this. It seems to be family related especially when member of the family suffer from asthma or even hay fever.

Another types of eczema whereby pain and burning is experienced along side with deep blisters is Dyshidrotic dermatitis which only occur on the hands and the palms of the hands as well as on the under parts of the feet and down the sides of the fingers and toes. This type falls under another name which is vesicular palmoplantar dermatitis and again doctors do not know what causes the onset.

Outbreaks of these types of eczema are common during the months of spring and summer as especially in very hot tropical climates and researchers are suggesting that this may be the primary cause of this type of eczema.

Nummular eczema which only really found in much older men and is found on the back, torso, arms and legs is diagnosed by crusted coin shaped areas and the person will complain of excess irritation and itchiness.

Usually there is a family history of atopic dermatitis as well as asthma and associated allergies which will ultimately increase the risks of developing nummular eczema and is seen as a chronic condition. And doctors have found nummular to be a very puzzling disease.

There is a vague possibility that dry skin could be one of the factors as well as medications that are used in the treatment of acne could be causing nummular dermatitis although the definite cause for this disease is unidentified. When there is an eruption the person must avoid coming into contact with substances like soap and washing liquids. If you go online there is a fortune of literature on these types of eczema.
