The Three Most Common Types Of Eczema

The medical fraternity have never been able to find out what causes eczema although it has been established that a malfunction of the immune system could be a cause. Various harsh substances could also be factors which are causing types of eczema for instance constant sweating, clothing fibres, and heavily perfumed cosmetics. Extreme changes in temperature as well as external allergens and stress could account for the onset of eczema.

One of the most common types of eczema is atopic dermatitis. This is a chronic skin disease which presents with itchy inflamed skin and is believed to be caused by abnormal function of the body's immune system. Atopic dermatitis tends to have its periods where it comes and goes and also depends on the triggering factors. Atopic dermatitis tends to run in the family and one will find that there is a family history of asthma or hay fever.

Another types of eczema which causes outbreaks on the hands especially the palm and the feet as well as along the sides of the toes which is characterized by clear, deep blisters that itch profusely as well as burn is known as Dyshidrotic eczema. The cause of this type of eczema is not known. This types of eczema is also known as vesicular palmoplantar dermatitis and around 20% of people have this condition.

This types of eczema is very common during the months of spring and summer and also common in tropical climates which may suggest that heat has something to do with the onset of this type of dermatitis.

Then there is the nummular eczema which presents with coin-shaped patches which is extremely irritating to the person and is commonly found on the lower legs, back, arms and buttocks. The area will either be crusted or flaking and is excessively itchy and is seen frequently in older men.


This could be an associated allergy especially if there is a history of atopic dermatitis in the family and if there is then there is obviously an increased risk of contracting nummular dermatitis and this condition is termed as chronic. This type of eczema is still puzzling doctors.

The causes of nummular eczema are unknown although there have been a number of factors which could be causing this condition like dry skin, low humidity, environmental and even some prescribed medications which are used for the treatment of acne could be the cause. There are substances that can worsen the condition like topical medications, detergents and soaps. Further literature is available online.
