Abstract
Foreign bodies in the breast are rarely encountered and may infrequently lead to complications such as persistent breast pain, abscess, and/or granuloma formation, pneumothorax, or cardiac tamponade. We aimed to present a case with a foreign body in her right breast, which was diagnostically missed in previous screenings. A 44-year-old asymptomatic woman, who was included in the national breast cancer screening program, was found to have a 2 cm-sized metallic foreign body in the upper-outer quadrant of her right breast via mammographic imaging. Retrospective clinical evaluations revealed that the foreign body had been present in her breast for at least five years. She was successfully treated via wire-assisted surgery. Although they may remain asymptomatic for long periods, foreign bodies detected in the breast are suggested to be surgically removed due to the possibility of considerable subsequent local or thoracic complications.
