A Case Report of Duodenal Adenocarcinoma with Diffusely Infiltrative Growth

Abstract

Duodenal adenocarcinoma with diffusely infiltrative growth is a rare tumor. This report presents a patient with a diffusely infiltrative duodenal adenocarcinoma that did not include marked ulceration. The patient's chief complaint was vomiting. The cancer was diagnosed on the basis of an endoscopic biopsy of the tumor. The patient underwent pancreaticoduodenectomy. Pathologic examination showed a duodenal carcinoma with diffusely infiltrative growth. The cancer was diagnosed as an annular-type duodenal adenocarcinoma because of the absence of marked ulceration.
