Duodenal Adenocarcinoma: a Case Report of an Uncommon Tumor and a Brief Review of the Literature

Duodenal adenocarcinoma is very rare. It represents 0.3 to 1% of all gastrointestinal malignancies. The symptoms are non-specific and vague, and the diagnosis is often delayed at an advanced stage. We report a case of duodenal adenocarcinoma in a 54-year-old female who was admitted to our hospital with chronic epigastric pain. Upper gastrointestinal endoscopy revealed a thickening narrowing the lumen in the second duodenal portion, which was diagnosed, using endoscopic biopsy. The computed abdominal tomography scan showed no lymph node or distant metastases, and cephalic pancreaticoduodenectomy was performed.
