Wat is Lichen Nitidus en Hoe Beïnvloedt het de Huid?

How Is Lichen Nitidus Diagnosed?

Treatment is rarely required, and there is no accepted cure for the condition. The bumps and other symptoms can go away in as little as one month or as much as one year, but sometimes for longer. Because the condition is not serious, the healthcare provider may reassure the affected person and not recommend treatment.

Treatments are available if the symptoms or cosmetic appearance are especially bothersome. The best treatment option depends on personal factors, such as what type of lichen nitidus you have, how you respond to treatments, and your healthcare provider's recommendations based on your overall health.

Some possible therapies for lichen nitidus include:

  • Topical or systemic corticosteroids to reduce inflammation levels
  • Immunosuppressant medications, including Protopic (tacrolimus)
  • Retinoids such as Soriatane (acitretin), especially if the hands and feet are affected
  • Phototherapy or exposure to sunlight, especially for generalized lichen nitidus
  • Photochemotherapy, which is exposure to UVA radiation after taking a medication that makes the skin more sensitive to light

After Effects of Lichen Nitidus

After the rash resolves, the skin may show post-inflammatory hyperpigmentation (darkened spots where the rash was). This can linger for months or longer.

Lichenoide Dermatosen

Eine heterogene Gruppe von wenigen, zum Teil aber keineswegs seltenen Dermatosen, die durch morphologische Merkmale charakterisiert ist (in Gruppen stehende entzündliche Knötchen, histopathologisch oft eine markante Entzündungsreaktion an der dermoepidermalen Grenzfläche). Hauptvertreter (und namensgebend) ist der verbreitete und vielgestaltige Lichen planus. Eine zweite Hauptgruppe sind die sehr häufigen lichenoiden Dermatosen durch chronisch-repetitives mechanisches Trauma (Kratzen): Lichen simplex chronicus und die Prurigodermatosen. Bei diesen handelt es sich um Dermatosen des Alltagslebens, die u. a. durch intensiven Juckreiz ausgezeichnet sind. Die Autoren ergreifen die Gelegenheit, um Ursachen und Genese des fundamentalen kutanen Phänomens Pruritus aufzugreifen und einen Überblick über die aktuellen therapeutischen Möglichkeiten zu geben.

What Causes Lichen Nitidus?

The cause of lichen nitidus is unknown. However, older studies examining the condition found that specific cells in the immune system, T lymphocytes, may play a role. These cells are designed to help the body fight off infection and disease.

One older study published in 2005 found that these immune system cells are activated in people with lichen nitidus. This research suggests that this is what's behind the condition's inflammation and bumps. The reason for the T-lymphocyte activation has yet to be discovered.

Who Gets Lichen Nitidus the Most?

Lichen nitidus is most often diagnosed in children and adolescents. It can affect people of any sex and ethnicity. Because the cause is unknown, medical researchers have difficulty determining who is more at risk. It may have a hereditary component, but research is still ongoing.

Currently, other health disorders have been linked to an increased incidence rate of lichen nitidus, including Crohn’s disease, Down syndrome, atopic dermatitis (eczema), and human immunodeficiency virus (HIV).
