Lichen simplex chronicus (LSC), also known as neurodermatitis, is a common chronic pruritic dermatitis characterized by lichenification of the skin caused by chronic itching and scratching.
Pathophysiology
Lichen simplex chronicus is not a primary process. Rather, a person senses pruritus in a specific area of skin (with or without underlying pathology) and causes mechanical trauma to the point of lichenification.
Clinical features
- Lesions on easy to reach areas
- Itching (M/C symptom)
- Plaques and thickened, potentially discolored lesions (may develop as a result of repeated scratching of the affected area)
Management
- Occlusion of the area (to prevent scratching)
- Topical anti-inflammatory therapies:
- Corticosteroids
- Topical emollients
- Antibiotics (if infection)
- Antihistamines (prevent exacerbation by allergic mediators)
