Dermatological diseases that cause red, itchy skin patches are collectively known as eczema. Eczema is not one single disease.

 This condition has several different names, including dermatitis, eczema (inflammation of the skin), and atopic eczema (a genetic predisposition to allergic hypersensitivity).

 Even though the terms “eczema” and “atopic dermatitis” are commonly used interchangeably, atopic dermatitis is the most common kind of eczema.

 The most severe and long-lasting form of eczema is Pathophysiology Atopic Dermatitis. When scratched, the red, swollen skin may break open and emit a clear fluid (an effect known as weeping). Flares, in which symptoms intensify, and remissions, in which symptoms improve or clear up, are standard in atopic skin conditions.


Eczema Comes in a Variety of Forms

 Atopic dermatitis is just one of several forms of eczema, but it is not the only one.


Consult with Eczema (Contact Dermatitis)

 An allergic reaction to a chemical in the environment creates red and itchy skin in this type of eczema.


Eczema of the hands

 A skin condition known as hand eczema manifests itself as dry, thick, scaly spots on the hands that are prone to cracking and bleeding (like contact dermatitis). A variety of irritants and allergies can cause hand eczema flares.


Eczema with Dyshydrotic Symptoms

 Dyshidrotic eczema may be diagnosed by the presence of small, irritating blisters on the soles of the feet and the edges of the fingers, toes, and palms. This type of eczema can be brought on by stress or allergens.


Eczema of the Nails

 Itchy, coin-shaped spots occur on the skin with nummular eczema, unlike other forms of eczema.


Stasis Dermatitis is a skin condition

 Due to a lack of blood flow, fluid seeps from the veins and into the skin.


Dermatitis seborrhoeica

 White or yellow scaly patches of skin appear in oily areas like the scalp (as in dandruff), face, and ears and are caused in part by skin-dwelling bacteria (such as some types of yeast).


Eczema Symptoms and Signs


Eczema causes dry, itchy skin and rashes all over the body, but it is most common on the face, hands, feet, elbows, and behind the knees for those who suffer from it. Wrist, ankle, neck, and mouth skin lesions, and blotches are other possible manifestations.

Eczema’s most common symptom is itching, which can lead to scratching and rubbing of the affected area, aggravating the condition even further on the body. The “itch-scratch cycle,” or increased itching and scratching that exacerbates eczema symptoms, can result from this.

eczema can cause a variety of other skin conditions, including:


  •         Skin that is rough and leathery in texture
  •         The red, elevated lumps have a reddish hue (hives)
  •         Skin wrinkles on the palms of the hands have gotten worse
  •         The face, upper arms, and thighs are covered in small, scratchy pimples.
  •         scaly spots on the body
  •         Inflamed and inflamed
  •         A shift in skin tone


Eczema Factors and Causes


As a result of reduced fat and oil production, skin affected with eczema has difficulty retaining moisture. It is also caused by a breach in the skin barrier, which allows the skin’s natural moisture to evaporate. As a result, it will dry out and lose its protective qualities.

Atopic dermatitis, the most common form of eczema, has no known etiology.

Children are more likely to get eczema if their parents have allergies, such as hay fever or asthma, which shows that the ailment is passed down down the generations.

Skin doctors may not consider eczema an autoimmune condition, but immune system overreaction or dysfunction is the cause of the symptoms of atopic dermatitis.
