Lichen Simplex Chronicus

Lichen Simplex Chronicus is a skin condition that causes areas of thickened, itchy skin due to repeated scratching or rubbing. It mainly affects the skin and can cause discomfort and visible changes in the affected areas. The constant scratching leads to a cycle of itching and skin thickening, which can make the problem worse over time. Commonly affected areas include the neck, scalp, ankles, and forearms. The skin may appear rough, scaly, and darker than the surrounding skin. This condition can interfere with daily activities due to persistent itching and skin irritation.

Lichen Simplex Chronicus is a chronic dermatologic disorder characterized by localized lichenification, which is thickening and exaggeration of normal skin markings caused by repetitive scratching or rubbing. It results from a self-perpetuating itch-scratch cycle often triggered by underlying pruritic conditions or psychological stress. Histologically, it shows hyperkeratosis, acanthosis, and dermal fibrosis. The condition is significant because it represents a secondary skin change rather than a primary disease, and it can lead to persistent discomfort and cosmetic concerns. It is important to distinguish it from other pruritic dermatoses and to identify any underlying causes. The chronic mechanical trauma leads to characteristic clinical and histopathologic features.
