title: Traumatic breast transposal to the abdominal wall: A case report.
abstract: Although abdominal wall masses are commonly observed in clinical practice, traumatic breast transposal appearing as an abdominal wall mass is a rare event. The unique phenomenon of a post-traumatic breast growing healthily in the abdominal wall has never previously been reported. The current study presents the case of a 40-year-old female who developed an unusually transposed, but healthy mammary gland in the right upper abdominal wall following a severe pedestrian traffic accident. In that accident, the powerful impact of the car caused multiple right-sided rib fractures, lung injuries and a protruding mass on the right abdominal wall. This sudden onset protruding mass was indicated to be breast tissue by computed tomography imaging and ultrasound scanning. The transposed mammary gland was resected and a pathological examination confirmed that it consisted of normal breast tissue. In this case, the force of the car caused no significant damage or necrosis to the right breast, but instead was sufficient to shift the mammary gland to the abdomen, where it grew healthily 6 months in its new location. This case highlights the capability of the mammary gland to withstand a powerful impact and survive. Moreover, it advances our knowledge of how mammary tissues respond to severe blunt-force impacts.
