title: Diffuse peritoneal deciduosis mimicking metastatic lesions.
abstract: A 32-year-old woman with an uneventful antenatal period underwent a caesarean section for breech presentation. At laparotomy, there were multiple yellowish elastic nodules distributed along the parietal peritoneal surface, totalling over 30 lesions and worrying the surgical team. The conclusive diagnosis of peritoneal deciduosis was supported by pathological analysis (histology and immunohistochemistry). The present case reports an uncommon presentation of diffuse peritoneal deciduosis mimicking metastatic lesions.
