LONG FOLLOW-UP STUDY OF ELEVATED SCAR OF ACUTE ANTRAL KISSING ULCERS

Abstract

It is very rare that gastric ulcer scar becomes elevated. We experienced a case of an elevated scar after healing of acute antral kissing ulcers and followed up the morphological changes for 3 years, especially a scar of the posterior wall. A 32-year-old man was admitted on November 22, 1979 because of sudden epigastric pain. Gastric juice showed hyperacidity. Endoscopic examination showed acute antral kissing ulcers which healed after 8 weeks. Five months later the scar of the anterior wall become a ha like lesion and the posterior one became a polypoid lesion with white coat. During observation for 3 years, the elevated lesion of the anterior wall unchaged but the posterior one became as the submucosal tumor after disappearance of the white coat. The histological finding of the polypoid lesion revealed remarkable edema, atrophic ducts and mild inflammatory cell infiltration but no hyperplastic change. When the polypoid lesion became as the submucosal tumor, the remarkable edema disappeared and the gastric mucosa was improved to almost normal appearance. From the above, we suggest that the elevated changes would be due to remarkable edema and inflammatory change.
