[Mastitis with abscesses caused by esophageal fistula].

Mastitis originating from a fistula from intramediastinal esophago-jejunostomy following gastrectomy is an extremely rare event. We report on a 79-year old woman who had undergone repeated surgery due to recurrent breast abscesses for more than a year. The patient's history showed gastrectomy and esophago-jejunostomy two years earlier, with subsequent undetected insufficiency of the anastomosis and inflammation of the breast. The reason for the recurrent breast abscesses was found intraoperatively to be due to a fistula which could be followed to the anastomosis. Histologically, vegetable tissue (food particles) was detected in the fistula specimen. Detailed assessment of the patient's history could have helped detecting the circumstances when the first breast abscess appeared. Exact preoperative diagnosis and accurate wound débridement could have revealed the real cause of the recurrent abscess formation much earlier.
