A CASE REPORT OF AN ELONGATED NON-NEOPLASTIC DUODENAL POLYP

Abstract

A 63-year-old female was referred to our hospital following the discovery of an abnormality in the upper GI tract during a medical examination. Endoscopic examination showed an elongated protrusion at the duodenal bulb, and an endoscopic polypectomy was performed. Histologically, the outer side was covered with normal duodenal mucosa and inner side consisted of proliferated Brunner's glands, loose connective tissue including dilated vessels and enlarged cystic glands of varying sizes. This case is considered to be identical with the concept of an intraluminal duodenal protrusion or an elongated non-neoplastic duodenal polyp as proposed by Inamoto et al. or Ezoe et al.
