Abstract
I would like to propose my opinions regarding whether psychogenic pruritus exists and how it could be defined. I also consider whether ‘functional itch disorder’ or ‘somatoform itch’ are more appropriate terms. In addition, we address how it can be understood, whether similar disorders exist, whether it is related to pleasure and how to diagnose and treat the patient. In our opinion, psychogenic pruritus does exist and is different from the aggravation of itch from other origins. It is aggravated by psychological factors and, therefore, it is necessary to separate the two terms. We believe that the major role of the brain in itch explains its pathophysiogeny.
