title: Gallbaldder perforation causing a subcutaneous abscess.
abstract: BACKGROUND
  This is a report of a rare case of an old woman with a large round mass in the right hypochondrium that was proven to be an abscess.
  
  
  METHODS
  A 82-year old woman with a firm round mass in the right hypochondrium was admitted for evaluation. The abdominal CT showed an abscess produced by a gallbladder perforation, and a gallstone impacted at the Hartmann's pouch.
  
  
  CONCLUSIONS
  The abscess was treated with a transcutaneous paracentesis, while the stone passed to the gastrointestinal tract through a cholecystoenteric fistula, without causing any further problems.
  
  
  CONCLUSIONS
  Gallbaldder perforation can rarely create a subcutaneous abscess especially in thin, elder subjects. Abscess drainage is the first line of treatment.
