[CME: Chronic Generalized Pruritus without Dermatological Cause]

CME: Chronic Generalized Pruritus without Dermatological Cause Abstract. Chronic generalized pruritus is a common symptom. Dermatological causes must be distinguished from non-dermatological causes. Non-dermatological chronic pruritus has many causes, such as systemic, infectious, neurological, psychogenic disorders, and drug-related side effects, some of which may be associated with significant morbidity. The possibility of a systemic disease should be considered in patients with generalized pruritus and no signs of primary skin lesions. In addition to a careful history and physical examination, selected laboratory examinations can be helpful in making a diagnosis. Pruritus can be the first sign of a malignant hematological disease. Pruritus associated with solid tumors is not that rare. This article offers an approach to chronic generalized pruritus in adults without concomitant skin changes with a viable clarification strategy and consideration of the most important differential diagnoses.
