Apotemnophobia, also known as xenomelia or body integrity identity disorder, is a rare condition characterized by a strong aversion or fear of a specific part of one's body, leading to a desire for it to be amputated or altered. Synonyms for apotemnophobia include acrotomophilia, dysmorphophobia, and somatoparaphrenia. Acrotomophilia can refer to a strong sexual attraction toward amputees, while dysmorphophobia encompasses a general fear or obsession with physical deformities. Somatoparaphrenia, on the other hand, describes the denial or unawareness of a limb or body part belonging to oneself. Although these terms have different nuances, they all relate to the complex condition of apotemnophobia and its manifestations.
