This should include information on the onset, extent (generalized vs.localized), severity, type of itch, aggravating and alleviating factors, diurnal and seasonal variations, bathing, occupation, hobbies, medication history and allergies, and past medical and surgical history.Pruritus or itch is defined as an unpleasant sensation of the skin that provokes the urge to scratch.It is a characteristic feature of many skin diseases and an unusual sign of some systemic diseases.Inquire about personal or family history of atopy (childhood eczema, allergic rhinitis, asthma), household and other contacts, pets, travel history, sexual history, and history of intravenous drug use (human immunodeficiency virus [HIV] or hepatitis C infection).If the patient has recently undergone surgery, ask if hydroxyethyl cellulose was used as a plasma expander, because this substance can be associated with intense generalized pruritus lasting for up to one year.Adapted from Pujol RM, Gallardo F, Llistosella E, et al: Invisible mycosis fungoides: A diagnostic challenge.

Examination of the upper midback can help in this distinction, because it is relatively inaccessible and unavailable for scratching.Administration of opioids in epidural anesthesia can also lead to pruritus.Itching is associated with dermatologic and systemic causes, and it is important to determine whether there is an associated skin eruption.Opioids have a central pruritic action and also act peripherally by augmenting histamine itch.Patients with tumors and lesions of the central nervous system have been reported to have intractable pruritus.
