  • Abstract
  • Look Inside

 A 58-year-old man who had undergone Billroth Ⅱ gastrectomy due to duodenal ulcer 28 years ago, was admitted to our hospital because of type Ⅰ early gastric cancer. Barium meal study and endoscopical examination revealed a protruding lesion in the anterior wall of the remnant stomach along the gastrojejunostomy site. The biopsy specimen revealed adenocarcinoma and, subsequently, subtotal gastrectomy was carried out. Macroscopically, the resected specimen showed an annular protrusion with nodular surface of the gastric mucosa at the stomal site.

 Histologically, the protrusion beared the features of gastritis cystica polyposa, with hyperplasia and cystic dilatation of the pseudopyloric glands and their submucosal invasion. Well differentiated tubular adenocarcinoma was noted in the superficial mucosa at the most elevated portion of the anterior wall of anastomotic site. Based on these findings it is speculated that type Ⅰ early gastric cancer has probably developed from gastritis cystica polyposa.
