Skin Picking updated LG 2010
The “skin picking” behaviour of PWS has a wide range of severity from patient to patient and sometimes in the same patient over time. A stability over time is more typical, however, as Wigren reported in 1999. Some patients have occasional minor skin picking while others maintain large open wounds. In the “PWS Personality” presented in 2006 we separated skin picking as a habit behaviour and self mutilation associated with extreme emotional distress, which is far less common. Here we will only address the former and leave the latter and rectal picking for another day.
