[Description of two cases of Munchausen syndrome by proxy]

The Munchausen syndrome by proxy, or Polle syndrome can be considered as a form of child abuse in which parents falsify or even produce a real pathology in their children submitting them to frequent hospitalizations and pointless medical examinations. The authors discuss two cases and emphasize the importance of an early identification of these cases to avoid psychical impairments that inevitably stem from this "new" form of child abuse.
