Recurrent chest wall abscesses overlying a pneumonectomy scar: an unusual presentation of a cholecystocutaneous fistula.

We report a case of recurrent chest wall abscesses overlying a right thoracotomy scar four years after a pneumonectomy for a right middle lobe bronchus squamous cell carcinoma. Exploration of the abscess cavities revealed no intra-thoracic or intra-abdominal communication. The patient developed sinuses in his thoracotomy scar and two years later, two gallstones were expelled from these sinuses. A cholecystocutaneous fistula was confirmed on a fistulogram.
