How Is Atopic Eczema Treated? continued...

Other drugs that might be used for patients with eczema include antibiotics (to treat infected skin) and antihistamines (to help control itching).

Phototherapy is another treatment that helps some people with eczema. The ultraviolet light waves found in sunlight have been shown to benefit certain skin disorders, including eczema. Phototherapy uses ultraviolet light, either ultraviolet A (UVA) or ultraviolet B (UVB), from special lamps to treat people with severe eczema.

Risks associated with phototherapy include burning (usually resembling a mild sunburn), dry skin, itchy skin, freckling, and possible premature aging of the skin. Your health care professionals will work with you to minimize any risks.

Can Atopic Eczema Be Prevented?

Currently, there is no effective strategy for preventing atopic eczema, but the symptoms of the condition can improve. To improve the signs of eczema: 

  • Reduce stress
  • Avoid scratchy materials (for example, wool) and chemicals such as harsh soaps, detergents, and solvents
  • Moisturize frequently
  • Avoid sudden changes in temperature or humidity
  • Avoid situations that cause sweating and overheating

 

Granuloma Annulare and Your Skin

Granuloma annulare is a chronic skin condition that consists of a circular-shaped rash with reddish bumps (papules).

Most often, the condition affects children and young adults. Granuloma annulare is slightly more common in girls and usually is seen in people who are otherwise healthy.

What Causes Granuloma Annulare?

The cause of granuloma annulare is unknown. 

What Are the Symptoms of Granuloma Annulare?

People who have granuloma annulare usually notice a ring of small, firm bumps over the backs of the forearms, hands, or feet. More than one ring may be noticed in some cases. The rash may be mildly itchy.

How Is Granuloma Annulare Diagnosed?

The condition is diagnosed by a doctor who may use a skin biopsy to confirm the diagnosis.

How Is Granuloma Annulare Treated?

Treatment of granuloma annulare often is not necessary, except for cosmetic reasons. In some cases, creams or ointments are used to help the bumps disappear. Some doctors may decide to freeze the lesions with liquid nitrogen or to inject steroids directly into the rings of bumps. Ultraviolet light therapy or oral drugs can be used in severe cases.

Lichen Planus and Your Skin

Lichen planus is a common skin disorder that produces shiny, flat-topped bumps that often have an angular shape and a reddish-purplish color. Lichen planus can occur anywhere on the skin but is often found on the insides of the wrists and ankles, the lower legs, the back, and the neck. Some people have lichen planus inside their mouth, genital region, hair, and nails. Thick collections of bumps may occur, especially on the shins.

Lichen planus occurs most often in adults aged 30 to 70. It is not common in very young or elderly people.
