What is Neurodermatitis (Lichen Simplex Chronicus)?

Neurodermatitis, also known as lichen simplex chronicus (LSC), is a chronic localized skin disorder resulting from a self-perpetuating itch-scratch cycle. Repetitive mechanical trauma to the skin produces well-defined, lichenified, hyperpigmented plaques most commonly on the nape of the neck, ankles, scalp, vulva, scrotum and forearms.

Triggers include atopic dermatitis, psoriasis, neuropathic itch (post-herpetic, brachioradial pruritus), psychological stress, anxiety and obsessive-compulsive features. Histopathology shows acanthosis, hyperkeratosis, hypergranulosis and variable spongiosis. The condition is more common in women aged 30-50 years and improves with consistent scratch interruption.

Lichenified skin with accentuated skin lines
Hyperpigmentation or hypopigmentation
