Nonpsychotic, nonparaphilic self-amputation and the internet.

The literature suggests that self-amputation is an outgrowth of either psychosis or paraphilia. In the case we present, the patient was neither psychotic at the time of amputation, nor did he ascribe a sexual motivation for his act. Instead, he had a long-standing idea that being an amputee was a critical aspect of his identity. The patient used the internet to research the method for his amputation and sought support from individuals with the same desire via e-mail, web sites, and Usenet news groups.
