What is Lichen Simplex Chronicus?

Lichen Simplex Chronicus (LSC) is a skin condition characterized by intense itching and a thick, leathery patch of skin that often appears as the skin's response to chronic scratching and rubbing. It is commonly referred to as neurodermatitis. LSC is usually caused by localized skin inflammatory conditions, such as allergies or irritants. It is most commonly seen in adults, although it can occur in children as well.

Symptoms of Lichen Simplex Chronicus

  • Itching
  • Leathery thickened skin
  • Small, raised, rough bumps
  • Skin excoriations
  • Redness
  • Sca recoverflaky, scaly skin

Causes of Lichen Simplex Chronicus

LSC is believed to be triggered by a variety of factors, such as allergies, skin irritants, and psychological stress. Allergic reactions may be triggered by contact with certain fabrics, cosmetics, or chemicals. Psychological stress could lead to scratching and rubbing, which can cause or worsen LSC.

Diagnosis of Lichen Simplex Chronicus

The diagnosis of LSC can often be made simply by examining the affected area. However, a skin biopsy may be needed in certain cases.

Treatment of Lichen Simplex Chronicus

Treatment of LSC generally involves avoiding the irritants that may cause or aggravate it, as well as controlling the itch and other symptoms. Topical corticosteroids may also be prescribed to reduce the inflammation, while topical calcineurin inhibitors, such as pimecrolimus and tacrolimus, may also be used. In severe cases, systemic medications may be necessary, such as prednisone, methotrexate, or cyclosporine.
