title: A case of unrelenting pursuit of castration.
abstract: OBJECTIVE
  Explore the limitations of the classification of body dysmorphic disorder.
  
  
  METHODS
  A chinese male relentlessly pursued castration to relieve painful erections which were never substantiated. The testes and corporaspongiosum had been removed. No psychotic symptom was prominent.
  
  
  METHODS
  Cognitive therapy and psychotropics were tried.
  
  
  RESULTS
  The remaining corpora cavernosa was removed subsequently.
  
  
  CONCLUSIONS
  The distorted somatic perception and secondary cognitive amplification (painful erections) could represent a variant of body dysmorphic disorder involving internal body image; diagnostic classifications should accommodate such a category.
