Similarities Between Eczema and Dermatitis

Dermatitis and eczema may seem like two vastly different skin conditions, but are actually pretty similar. Any inflammation of your skin is known as dermatitis and eczema is a type of dermatitis caused by specific infectious pathogens. So while all eczemas are dermatitis, not every dermatitis is eczema. Doctors use these two terms alternatively for the skin condition that causes flaky skin with red dry patches and even itchiness.

Major Differences Between Eczema and Dermatitis

1. Definition and Key features

Dermatitis

It is a chronic skin condition that causes red rashes and itchiness. It mostly occurs on the joints of your body such as knees, elbows, and around the neck. Dermatitis [1] is typically associated with infectious pathogens like fungi, bacteria, yeast and viruses. People with mild to severe dermatitis may also suffer from asthma and hay fever.

Atopic dermatitis can happen even at a very early stage of life as in childhood. It is a long-lasting skin condition and may recur from time to time.

Eczema

Eczema is a commonly used term for a skin condition that causes itchy rashes. Atopic dermatitis is one of the primary types of eczema. Since eczema causes itchiness and discomfort, you mostly tend to scratch it, which inflames your skin, worsening the condition. Your skin also turns bumpy.

Eczema mostly happens among children but adults can also get affected by it. The rashes appear on your wrists, face, feet and hands.

2. Triggers

Dermatitis

Environmental And Genetic Factors:

These may lead to a constant tendency towards itching and inflamed skin. Most studies suggest that it is associated with atopic disorders like asthma and hay fever. So people who have dermatitis may have hay fever and asthma as well.

Filaggrin Decrease:

When the filaggrin (a protein) decreases from your skin, it disturbs your skin’s normal hydration which may lead to dermatitis.

Food Allergies:

Sensitivity or allergy to certain foods can also cause dermatitis. You may get extreme itching and discomfort due to this skin condition.

Weak Immune System:

According to studies and surveys, many patients who have faced this skin condition also had weak immune systems.

Infections:

Fungal infections, cutaneous staphylococcal infections, lip infection, herpes, smallpox can trigger dermatitis.

Eczema

Allergens:

Contact with allergens, latex gloves and certain metals can lead to eczema. Hand eczema [2] occurs when your hands come in contact with an allergen causing blisters on the soles of your feet and hand. Follicular eczema [3] occurs in your hair follicles as a secondary reaction to certain irritants.

Toxic Chemicals:

Constant exposure to toxic chemicals, usage of harsh soaps, fragrant cosmetics, pepper spray, bleach, exposure to kerosene, battery acid and chemicals can lead to eczema. Topical steroids, toothpaste with fluoride can trigger eczema too.

Injuries, Bites And Infections:

Burn injuries, insect bites and abrasion can cause Nummular eczema [4], which appears as coin-shaped itchy patches. A kind of herpes virus may also cause burning, blistering rashes on your skin. Yeast infections can cause Seborrheic dermatitis [5], a chronic eczema in the scalp or areas with most hair follicles.

Weather And Skin Type:

Neurodermatitis, a neurological skin condition causes scaly and itchy skin on your hand, scalp, feet and neck. The cause behind this is unknown but it is mostly associated with dry skin. Ear eczema happens due to extreme weather conditions and makes your skin dry and scaly.

Other Triggers:

Hot showers taken over a long period and usage of uncomfortable fabric are some of the other triggers.
