ABSTRACT

It is reasonable to assume that all humans itch at some point in their lives, but the incidence and prevalence of itching remains unknown.

The discussion in this chapter will be limited to several skin diseases and systemic diseases where itch is an important factor, or where itch has not been well described before. We will present highlights and will not discuss all the itchy dermatoses. The reader is referred to complete textbooks for indepth discussion.
