[Spontaneous cholecystocutaneous fistula presenting in the right breast].

We report a case of an 89 year-old woman, with an abscess in the right breast. On incision the abscess produced bile. Ultrasound scan, computed tomography, magnetic resonance imaging and endoscopic retrograde cholangiopancreatography showed a fistula from a subphrenic abscess to the breast. Conservative treatment was insufficient and the condition only resolved after open cholecystectomy. During the latest 50 years, less than 20 cases of cholecystocutaneous fistula have been reported. Perforation to the breast has not previously been described.
