| Abstract |
|
Gallbladder cancer (GBC) is the most common primary hepatobiliary carcinoma and the sixth most common gastrointestinal malignancy. Adenocarcinoma accounts for the vast majority of GBCs (80–95%), whereas squamous cell carcinoma constitutes only 0–3.3% of GBCs. A 69-year-old man was suspected to have GBC with a cholecystoduodenal fistula on an abdominal computed tomography scan. He underwent esophagogastroduodenoscopy, which revealed that the duodenum was obstructed by the mass. Duodenal and biliary stents were successfully placed using endoscopic retrograde cholangiopancreatography. Pathology obtained from the duodenum revealed the mass to be a squamous cell carcinoma. |
