A case of duodenal adenocarcinoma of the third portion

Abstract

We report a rare case of primary duodenal adenocarcinoma of the third portion.
A 57-year-old man was admitted due to vomiting. An abdominal CT scan revealed wall thickening of the third portion of the duodenum. The barium meal examination of the upper GI tract and endoscopy of the duodenum showed stenosis and a circular tumor of the third portion of the duodenum, and biopsy disclosed moderately differentiated adenocarcinoma.
Pancreatoduodenectomy with regional lymph node dissection (R0 resection) was performed. Histological examination disclosed that the tumor was moderately differentiated adenocarcinoma invading through the subserosa to the peri-duodenal fat tissue with lymph node metastasis.
