We present a rare, atypical case of a 24-year-old transgender male (assigned as a female at birth) admitted to the hospital after the planned self-amputation of his left hand. The patient described his motivation for this self-amputation as coming from deep-rooted and persistent feelings that this hand was not a part of his body. He identified himself as having, according to internet peer group definition, body integrity identity disorder. This condition is now referred to as body integrity dysphoria (BID). This patient was later diagnosed as having gender dysphoria and other conditions, including bipolar disorder and gaming disorder. The follow-up 2 years after self-amputation is presented, during which, despite antipsychotic and antidepressant treatment, the symptoms of BID remained unchanged and the high variability of other psychopathology was observed. This is an unusual case of BID simply because several other comorbidities are presented. Like many other rare clinical situations, this case also presents a particular challenge to our understanding of the dynamics and interrelationships between comorbidities, raising concerns and questions.
