Lichen simplex chronicus

Lichen Simplex Chronicus (LSC), also known as Neurodermatitis Circumscripta, is a skin disorder characterized by chronic itching and scratching. The constant scratching causes thick, leathery, brownish skin.

Causes

Lichen Simplex Chronicus is not a primary disease but a result of chronic scratching or rubbing of the skin. The exact cause of the itch is not known, but it may be due to stress, anxiety, or other psychological issues. It can also be triggered by dry skin, insect bites, or skin irritation from tight clothing.

Symptoms

The primary symptom of Lichen Simplex Chronicus is an intense itch, which leads to scratching. This scratching further irritates the skin, leading to a cycle of itching and scratching. Over time, the affected skin becomes thick, leathery, and darkly pigmented. The most commonly affected areas are the neck, wrist, forearm, thigh, ankle, and the genital area.

Diagnosis

Diagnosis of Lichen Simplex Chronicus is primarily based on the appearance of the skin and a history of chronic itching and scratching. A skin biopsy may be performed to rule out other skin diseases.

Treatment

Treatment of Lichen Simplex Chronicus involves breaking the itch-scratch cycle. This can be achieved through the use of topical corticosteroids, antihistamines, and in some cases, psychotherapy or counseling. In severe cases, systemic corticosteroids may be used.

Prognosis

With treatment, the prognosis for Lichen Simplex Chronicus is generally good. However, the condition can be difficult to manage and may recur, particularly if the underlying cause of the itch is not addressed.
