Its clinical and radiological presentations are similar to those of cholangiocarcinoma, and its management requires collaboration between surgeons, endoscopists, and oncologists.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case presentation:<\/jats:title>\n                    <jats:p>We present a unique case of a 58-year-old woman previously treated two and a half years ago for middle rectal adenocarcinoma with liver metastasis. In the immediate postoperative period, following restoring digestive continuity, she presented cholestatic jaundice from malignant obstruction of the extrahepatic bile duct. A midline laparotomy revealed a tumor of the common bile duct invading the hepatic pedicle. Therefore, external bile drainage, biopsy and hepatic lymph node dissection were performed. Immunohistochemical staining confirmed the diagnosis of extrahepatic bile duct metastasis from rectal adenocarcinoma.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Clinical discussion:<\/jats:title>\n                    <jats:p>Extrahepatic bile duct metastasis from rectal adenocarcinoma manifests as bile duct stenosis or intraluminal lesions, and only pathological examination with immunochemical staining confirms the diagnosis.
