TWO CASES OF DUODENAL BRUNNER'S GLAND TUMOR DISSIMILAR IN ENDOSCOPIC AND HISTOLOGICAL CHARACTER

Abstract

We experienced two cases of duodenal Brunner's gland tumor dissimilar in endoscopic and histological character. Case 1: tumor was elastic soft, histologically showed a simple hyperplasia of Brunner's gland. Case 2 : tumor was a pale elastic hard submucosal tumor with depression at the top, histologically showed a nodular proliferation, connective tissue with smooth muscle fiber. The duct-like structures formed by glandular epithelium probably open out the depressed lesion in the surface of tumor. This case would best be classified as a hamartoma of Brunner's gland.
