Dermatitis is a general concept that includes various skin diseases. All of them are inflammatory in nature. Depending on what caused the disease, there are several basic types of dermatitis. The disease can be affected by different parts of the body. But as practice shows, most often you have to suffer hand and foot. In second place in the frequency of lesions - the face. On the body, the symptoms of the disease are diagnosed least often.
The main types of dermatitis
There are two main groups of causes that cause disease:
- contact with irritants;
- internal diseases (in this case, rashes - just a symptom of a more serious problem).
Proceeding from this, experts distinguish and different types of dermatitis, manifested in the form of plaques, small papules and pimples:
- The contact form of the disease develops as a result of exposure to the skin of a certain irritant: a chemical, ultraviolet rays, high temperatures. As a rule, this type of dermatitis spreads only to those areas of the epidermis, which had to come into contact with an irritating factor.
- Dermatitis of seborrheic appearance is accompanied by very unpleasant symptoms. The skin begins to peel and flake flakes. The hairy part of the head mostly suffers. Develop the disease can all, but people from 20 to 50 years to monitor health is recommended with special attention.
- The stagnant form of the disease affects in most cases only the limbs. The cause of this form of dermatitis is in the liquid accumulated under the skin.
- The rash with perioral dermatitis is concentrated in the nasolabial area.
- Atopic dermatitis and its allergic appearance are identical in symptoms. And they are caused by the same allergens. The main difference is that the allergic form develops due to the action of one pathogen, while the atopic form is simultaneously several.
