Itch is one of the cardinal symptoms of polymorphic light eruption (PLE), the most common form of photodermatosis known to be mediated immunologically. Indeed, very often itch precedes the skin lesions of the condition or may be even the only symptom in PLE, which sometimes is aggravated to a burning sensation. There have been reports of a variant called PLE sine eruption, with intense pruritus on the sun-exposed parts without any visible skin changes. This article is protected by copyright.
