Category: Dermatological diseases

Disease Definition:

Lichen nitidus consists of tiny, skin-colored bumps (papules) that usually appear in clusters on the surface of the skin, particularly on the trunk and upper extremities. It is rare and noncancerous. Its exact cause is still not known.

 

Usually, lichen nitidus affects children and young adults, but it could develop in anyone. Though this condition is annoying, but it is harmless. Over time, lichen nitidus usually disappears, sometimes even without treatment.

Symptoms, Causes

Symptoms:

This condition usually appears as numerous skin-colored, shiny papules on the skin. These pinpoint- to pinhead-sized bumps could resemble warts, and usually appear in clusters. The skin surfaces where these papules usually occur include:

 

  • Arms and the back of the hands
  • Genitalia
  • Body trunk

 

Some of the less frequent sites where lichen nitidus occurs include:

 

  • Mucous membranes
  • Palms of the hands and soles of the feet
  • Fingernails or toenails

 

Lichen nitidus doesn't cause any symptoms except for itching in some cases.
 

Causes:

The exact cause of lichen nitidus is still not known. However, it could sometimes occur with these conditions:

Amenorrhea:

This condition is the absence of a monthly menstrual period.

Lichen planus:

An itchy rash on the arms, legs and trunk, and soreness in the mouth will be caused by this inflammatory skin condition.

Juvenile rheumatoid arthritis:

This is a painful and chronic swelling of the joints that affects children.

Crohn's disease:

An ongoing inflammation of the intestinal tract could be caused by this disease.
 

Complications

Complications:

Even though lichen nitidus could be cosmetically troubling, but it doesn't cause any medical complications.
 

Treatments:

A person may decide not to treat lichen nitidus at all because it is a harmless condition and usually gets better on its own after several years. However, someone could choose to treat it for cosmetic reasons. Some of the treatment options for this condition may include:

Phototherapy:

This technique is used in treating a variety of skin disorders. In this method, the skin is exposed to natural or artificial light (ultraviolet light).

Antihistamines:

These medications could help relieve itchy skin. They inhibit a chemical called histamine, which is involved in the body's immune response.

Retinoids:

Skin cell growth could be regulated by retinoids, which are derived from vitamin A.

Steroids:

To reduce inflammation, corticosteroids could be applied on the skin (topical).

 

To determine which of these therapies will be most useful, a person could ask the help of a doctor.
