According to the site, this is an example of Body Integrity Identity Disorder, (BIID) or Apotemnophilia.

A little background research for those of you interested:

"Body Integrity Identity Disorder (BIID), also known as Amputee Identity Disorder or Apotemnophilia (from Greek αποτέμνειν "to cut off", and φιλία "love of") is the overwhelming desire to amputate one or more healthy limbs or other parts of the body. Sometimes its sufferers take it upon themselves to amputate their own limbs and/or penis. Although it most commonly refers to people who wish to amputate limbs, the term BIID, or 'wannabe' also applies to those who wish to alter their bodily integrity." (Wikipedia)

BIID seems to be considered somewhat of an extreme case of the emotional needs characterized for hypochondria/Munchausen's combined in part with body dysmorphia, with sufferers wishing for a different body or for the attention and care that they connect with being an amputee. An interesting theory is that BIID is caused by a problem with proprioception, making sufferers feel that they are somehow incomplete or "wrong".

I don't have the time to think this out completely, but my initial reaction is that this is a horrible thing, and should be prevented whenever possible. I just don't see how allowing people to cripple themselves could possibly be looked on as proper or even just acceptable by our society.

Perhaps part of my reaction is due to the fact that I know several amputees, all of whom would pay mindblowing prices (not merely monetary, mind you, emotional and relationship-wise) for a chance to regain the use of their missing limb.

Ugh. I'm going to go vomit.

Excellent research rembar, thanks.
And yes, this person definitley needs psychological help.

why not amputee his brain...?

The problem is that their condition is very severe. These people are extremely unhappy and depressed until they can get themselves rid of the body part that torments them.

I would argue that the problem is that they sincerely want to remove perfectly functional and healthy limbs from their bodies. But that's just me.
