Dermatitis: Types of Dermatitis

Allergic Contact Dermatitis 

An allergic reaction, also known as allergic contact dermatitis or allergic eczema, can be brought on by an allergen, a substance that comes into contact with the skin. The allergen is safe for individuals who are not allergic to it. A different name for allergic contact dermatitis is contact allergy.

Individual occupational groups and members of the general public commonly encounter allergic contact dermatitis.

It affects women more frequently than men, mostly because of nickel allergy and, more recently, acrylate allergy connected to nail cosmetics.

Children with nickel allergies are also rather prevalent.

Topical contact allergies to antibiotics are common in adults over 70.

Metalworkers, beauticians, hairdressers, nurses, cleaners, painters, and florists are among the professions that experience allergic contact dermatitis most frequently.


Irritant Contact Dermatitis


An irritant is the most common type of contact dermatitis. A non-allergic skin reaction happens when an allergen damages your skin's outer, protective layer. Some people can develop sensitivities to strong irritants after just one exposure. Some people may get a rash after being repeatedly exposed to even mild irritants, like soap and water.

Atopic Dermatitis

A chronic (long-lasting) disorder that causes skin irritation, redness, and inflammation is eczema, also known as atopic dermatitis. It is a common illness that primarily affects children, although anyone can develop it at any age. Atopic dermatitis cannot be transmitted from one person to another since it is not communicable.


Hand Eczema

Does dermatitis cause eczema on the hands? The condition known as hand dermatitis or hand eczema affects about 10% of people in the US. Genetics, contact allergies, and irritating chemicals can all act as "triggers" for this particular type of eczema.

Eczema on the hands also referred to as hand dermatitis, is a skin condition that itches. It results in broad, itchy, scaly, and colorful rashes on the hands and fingers. Blisters and cracks in the skin can be quite painful.

Hand eczema is more common in people who have a history of atopic eczema and are frequently exposed to water and chemicals. For instance, this might be true of hairdressers, maids, cooks, and medical professionals.



Neurodermatitis, a non-life-threatening skin condition, causes itchiness and scratching, usually on one or two small patches of skin. Lichen simplex chronicus is another name for it.

Although it can occur anywhere on the body, the scalp, back of the neck, arms, shoulders, and elbows are where it seems to manifest most frequently. Additionally, the anal, vaginal, and facial areas could itch. The itching may be intermittent or continuous, necessitating frequent scratching. It is most active when the patient is relaxing or making an effort to sleep. The wounded area may be rubbed or scratched when the patient awakens sometimes.

Nummular Dermatitis

Nummular dermatitis is a pruritic eczematous dermatosis that is characterized by many coin-shaped lesions. It may be a symptom of stasis dermatitis, asteatotic eczema, or atopic dermatitis. The prognosis for this ailment is excellent.

An inflammatory skin condition known as eczema or nummular dermatitis is characterized by the development of distinct round to oval erythematous plaques (nummular means round or "coin shaped"). The term "nummular dermatitis" has also been used to describe the lesion morphology that can be seen in many other disorders, such as atopic dermatitis, contact dermatitis, and asteatotic eczema. The primary topic of this discussion is the illness entity that has been covered in the literature. Eczema has been referred to by other names like discoid or orbicular.


Seborrheic Dermatitis 

Seborrheic dermatitis is a normal skin condition that predominantly affects your scalp. It causes scaly patches, flaky dandruff, and skin discomfort. The common oily body areas that are impacted are the face, sides of the nose, eyebrows, ears, eyelids, and chest.

Seborrheic dermatitis is one of many contagious, easily managed skin disorders. This kind of dermatitis is characterized by oily scales, white, yellow, or powdery flakes on your scalp, and patches of itchy red skin. "Seborrheic" alludes to sebaceous glands, whilst "derm" denotes the skin.


Stasis Dermatitis 

One of its main causes, varicose veins, stasis dermatitis, also known as varicose eczema, refers to the skin irregularities that appear on the leg as a result of blood pooling due to insufficient venous return.
