Varieties of the disease.
A single classification of eczema in dermatology does not exist, but most doctors identify the main forms of skin disease. Depending on the location of the species, the pathogen types are different types of eczema.
The true eczema and its variety is a dysgidrotic
True eczema is an inflammation of the skin in chronic form. A characteristic area of skin damage is the face, neck, hands, feet. At an early stage of the disease, small redness appears with uneven edges on these areas of the skin.
The patient in the inflamed area feels strong carding. After a while, blisters with a clear or turbid liquid form in their place. Soon the affected areas burst, forming a crust on the surface. Then they coarsen, change color, and cracks can form. On the hands, soles, there is an excessive thickening of the skin.
Callusiform or dyshidrotic form
It is localized only on the palms and sole of the foot. As a rule, it develops with the disturbed perspiration or negative influence of chemical toxic substances. At the beginning, a characteristic rash of red color appears on the palms of the hand, then it moves to the plantar part. The rash has clear boundaries, it is small blisters filled with liquid of transparent color.
This form arises after a long contact of a person with industrial or household chemical preparations. A typical area of damage is the face, neck, inner part of the palms, forearm zone.
Originated in areas infected with microbes or fungal infection. As a rule, it is the lower leg, the foot, the back part of the auricle. The area of the lesion has rounded borders, which are clearly separated from the healthy skin.
The foci of inflammation are covered with dense crusts of greenish or yellow color. Their formation is often accompanied by a process of festering. When they disappear, a wetting surface with a bluish-pink hue appears in their place. For the borders of the lesion, it is characteristic to grow into a large area where healthy skin is not visible.
After the disappearance of the crusts, the skin of the patient remains dry, shiny with a slight reddening.
A coin or nummular disease
It affects the older men. Dermatologists note that the recurrence of the disease manifests itself in the autumn and winter periods. On the arms, legs, back of the patient appear round rashes resembling coins. For this type of characteristic rash, which is covered with crusts with yellow or brown.
From the inflamed place it is possible to separate pus with a small amount of blood.
One of the main signs of a noummular disease is an itch of different intensity. The more acute the course of the disease, the greater the feeling of carding of the affected areas.
After complete recovery, the epidermis in the area of the lesion is dry and flaky.
This disease, which accompanies varicose veins and other changes in blood vessels. These pathologies are characteristic of elderly patients. Foci of inflammation - the gastrocnemius.
One of the main causes of varicose eczema is stagnation in the blood vessels of the legs. Signs of the disease develop gradually.
The clinical picture of this form is as follows: in the zone of varicose veins appear small spots of bright red, violet, cracks, blisters.
The patient feels strong carding, which worsens at night. Small blisters can form on the skin, which are filled with liquid.
Soon the blisters burst, forming crusts. Then the skin coarsens, it is painted in a dark brown color. In the chronic stage, ulcers that do not heal for a long time are formed.
Common signs of the types of eczema
Typical clinical features are typical for all types of disease:
- erosion or serous wells, from which a serous fluid is released;
- cornification of the superficial dermis;
- bloody or purulent inflammation of the external cover;
- the appearance of seals on the surface of the skin;
- multiple epidermal lesions of bright red color, covered with cracks, wounds.
Despite the peculiarities of each type of eczema, dermatologists distinguish two stages during the course of the disease.
- Acute stage - the intercellular edema of tissues is formed, the keratinization of the epidermis surface. There are small blisters filled with a transparent serous fluid. Affected areas become wet, there may be purulent or spotting.
- Subacute stage - the inflammatory process decreases, there remains a small number of blisters, edematous phenomena in a less pronounced form. The place of bursting bubbles is characterized by the formation of thickening of the epidermis surface, trophic ulcers.
