This is a case report of two patients with chronic plaque psoriasis in whom cutaneous nerve damage resulted in clearance of the disease at that site. In both patients reappearance of the psoriasis occurred with recovery of cutaneous sensation. The role of cutaneous sensation in the maintenance of skin disorders and, in particular, the role of neuropeptides in the pathogenesis of psoriasis are discussed.
