Lichen Simplex Chronicus

What is Lichen Simplex Chronicus

Lichen Simplex Chronicus may represent the end stage of a variety of pruritic and eczematous disorders. It consists of a well-circumscribed plaque or plaques with lichenified or thickened skin due to chronic scratching or rubbing.

Common areas involved include the posterior nuchal region, dorsum of the feet, or ankles.

Causes and Treatment of Lichen Simplex Chronicus

Treatment of Lichen Simplex Chronicus centers around breaking the cycle of chronic itching and scratching, which often occur during sleep. High-potency topical glucoocorticoids are helpful in alleviating prutitus in most cases, but in recalcitrant cases, application of topical glucocorticoids under occlusion or intralesional injection of glucocorticoids are required.

Patients need to be counseled regarding driving or operating heavy equipment after taking these medications due to their potentially potent sedative activity.
