Definition

 

Lichen simplex chronicus or nodular prurigo refers to a cutaneous response to rubbing or scratching normal skin.

 

Aetiology

 

More common in Asian, African and Oriental patients and is associated with atopic tendency.

 

Clinical features

 

Following intense itching and recurrent scratching of a patch of skin, lichen simplex chronicus presents as a single plaque often on the lower leg, neck or the perineum. Nodular prurigo presents as multiple itchy nodules, which are more diffusely distributed.
