Answer

Pruritus, or itch, is most commonly associated with a primary skin disorder such as xerosis, atopic dermatitis, drug eruption, urticaria, psoriasis, arthropod assault, mastocytosis, dermatitis herpetiformis, or pemphigoid. However, when a primary skin condition cannot be identified as the cause of pruritus, then a systemic or neuropathic cause must be sought. Patients without signs of a primary skin condition should undergo a thorough evaluation of potential systemic causes of itching.
