Abstract

We report an extremely rare case of metastatic common bile duct cancer from pulmonary adenocarcinoma presenting as obstructive jaundice. The patient was a 76-year-old male, who presented with generalized weakness and right upper quadrant pain. Plain chest X-ray noted multiple small nodules in both lung fields. Abdominal computed tomography scan showed a stricture of the mid common bile duct along with ductal wall enhancement. Endoscopic retrograde cholangiography revealed a concentric, abrupt narrowing of the mid-common bile duct suggestive of primary bile duct cancer. However, pathology comfirmed metastatic common bile duct cancer arising from pulmonary adenocarcinoma with immunohistochemical study with thyroid transcriptional factor-1 (TTF-1).
