Spontaneous cholecystocutaneous fistula presenting with an abscess containing multiple gallstones: a case report.

Spontaneous cholecystocutaneous fistula is a rare complication of chronic calculous cholecystitis. This complication, a result of the natural history of gallbladder stones, was formerly common. Today it is rare, because of early diagnosis and treatment of biliary tract diseases. We report a case of spontaneous cholecystocutaneous fistula in a 70-year-old female patient who presented with an abscess formation in the right upper quadrant. After the incision of this infective focus, many gallstones were picked up. One-stage open cholecystectomy and excision of the fistula tract were carried out after control of the abdominal wall infection.
