BIID or Body Integrity Identity Disorder is according to Wikipedia "the overwhelming desire to amputate one or more healthy limbs or other parts of the body." The Leiter Reports: A Group Blog has an interesting post on the philosophical and ethic issues involved in amputating healthy limbs. It includes links to other sources including "Amputees by Choice: Body Integrity Identity Disorder and the Ethics of Amputation" in the Journal of Applied Philosophy.
