title: Human "autotomy".
abstract: We describe two cases of self-injurious behaviour. One was a man with central post-stroke pain with maximal pain in the tip of the nose, who excavated his ala nasae--in which he subsequently continued to experience phantom pain. The second case a man who, following ophthalmic herpes zoster and possibly mild postherpetic neuralgia. He subsequently scratched his anaesthetic forehead down to the bone, while denying he experienced any pain. We would describe the first case as one of true autotomy; but the second as destruction of an anaesthetic part of the body. The implications for human and animal physiopathology are discussed.
