  • Abstract
  • Look Inside

 A 53-year-old woman, who had suffered from recurrent gastric ulcer for previous twelve years, visited our hospital because of a giant gastric ulcer found by x-ray studies. Endoscopy showed a gastric ulcer more than 30mm in diameter in the anterior wall of the gastric angle, at the end of a long linear ulcer scar. Almost whole margin of the ulcer was smooth, but a small irregular depressed lesion was recognized at its anal side. Biopsy specimens taken from the margin of this depressed lesion revealed cancer cells. Review of the endoscopic findings retrospectively showed a discolored area less than 5mm in diameter adjoining to the irregular depressed lesion. Histological examination of the resected specimen showed that the irregular depressed lesion did not contain any cancer cells and was covered with regenerative mucosa. Adjacent to the regenerative mucosa a Ⅱb lesion measuring 8mm in diameter was observed. The histological diagnosis was as being tubular adenocarcinoma and the lesion was limited within the mucosa. It was suggested that the ulcer margin had been separated from the cancer focus by extending regenerative epithelium during the process of ulcer healing.
