Highlights & Basics
- Lichen simplex chronicus may occur as a primary process with no underlying dermatosis or as a secondary process due to an underlying pruritic dermatosis (such as atopic dermatitis or allergic contact dermatitis) or a systemic condition causing pruritus.
- Underlying psychological comorbidities may be present including depression, anxiety disorder, or obsessive-compulsive disorder.
- A difficult to manage and often recurring condition that is treated with potent topical corticosteroids and sedating antihistamines.
