Dermatitis

At Magnolia Medical & Aesthetics San Antonio, we effectively treat various types of dermatitis with prescribed medications.

Dermatitis, also known as eczema, is a group of diseases that results in inflammation of the skin. These diseases are characterized by itchiness, red skin and a rash. In cases of short duration, there may be small blisters, while in long-term cases the skin may become thickened. The area of skin involved can vary from small to the entire body.

Most types of dermatitis can be diagnosed by a doctor’s observation of the irritation and its location on the body.

Sometimes a skin scraping will be taken for microscopic analysis. To identify causes of allergic contact dermatitis, we may use patch tests, which involves the application of suspected allergens to areas of skin on the back.

Types of Dermatitis

There are many types of dermatitis, or inflamed skin disorders, including:

WHAT IS IT?
That red, itchy rash on your scalp that has flaky scales could be seborrheic dermatitis, or seborrhea. It’s a common skin disease that looks similar to psoriasis, eczema, or an allergic reaction. And it can appear on your body as well as your scalp.

CAUSES
It is not known what exactly causes seborrheic dermatitis. It seems to be a combination of things, including:

  • Stress
  • Your genes
  • A yeast that normally lives on skin
  • Certain medical conditions and medicines
  • Cold, dry weather

Newborns and adults aged 30-60 are more likely to get seborrheic dermatitis. It’s more common in men than women and in people with oily skin.

WHAT IS IT?
Atopic dermatitis (eczema) is a condition that makes your skin red and itchy. It’s common in children but can occur at any age. Atopic dermatitis is chronic skin condition and tends to flare periodically. It tends to resemble an allergy, but it is not an allergic reaction.

CAUSES
The current thinking is that atopic dermatitis is caused by a combination of factors that include::

  • Genetics
  • Abnormal function of the immune system
  • Environment
  • Activities that may cause skin to be more sensitive
  • Defects in the skin barrier that allow moisture out and germs in

WHAT IS IT?
Nummular dermatitis or discoid eczema, is a chronic condition that causes coin-shaped spots to develop on the skin. These spots are often itchy and well-defined. They may ooze clear fluid or become dry and crusty. The lesions frequently develop on the arms or legs, but they may eventually spread to the torso and hands.

CAUSES
It often appears after a skin injury, such as a burn, abrasion, or insect bite. The condition may result in one patch or multiple patches of coin-shaped lesions. The patches can last for several months.

WHAT IS IT?
Allergic contact dermatitis is a form of contact dermatitis, in which the skin is injured by friction, environmental factors such as cold, over-exposure to water, or chemicals such as acids, alkalis, detergents and solvents.

CAUSES
Allergic contact dermatitis occurs when the skin develops an allergic reaction after being exposed to a foreign substance. This causes the body to release inflammatory chemicals that can make the skin feel itchy and irritated.

This condition develops in people who have poor circulation. Because poor blood flow usually occurs in the lower legs, this is where stasis dermatitis often develops. It may occur in one or both legs. Stasis dermatitis can develop in other areas, but this is rare.

Stasis dermatitis is most common in the lower legs because leg veins have one-way valves, which play an important role in circulating our blood. These valves push blood up the legs

SYMPTOMS
Swelling around the ankle is often the first sign of stasis dermatitis. The swelling tends to clear while you sleep and return during the day. Other early signs are discolored skin and varicose veins.
