Elevation of the Ulcer Base in Cases Treated with an H2‐Blocker —Difference between an Elevated Type of Gastric Ulcer Scar and a White Elevated Lesion—

Abstract

Abstract: A white elevated lesion (WEL) was noted in 7 out of 227 ulcer patients treated with an H2‐blocker. These were compared with eight patients with an elevated type of gastric ulcer scarsThe elevated type of gastric ulcer scar (ES) is an elevated lesion covered with regenerating epithelium, showing no whitish exudate, and is foveolar hyperplasia in the histological picture of biopsy. The period prior to the formation of an elevated lesion was as short as 4 weeks on average, and the formed elevated lesion retained the elevated from for as long as several months to several years.The WEL is an elevated lesion covered with whitish exudate, and shows granulation in the histological picture of biopsy. The period prior to the formation of an elevated lesion was as short as 3 weeks on average, and the formed elevated lesion became flattened in a relatively short period of several weeks to several months.From the above results the ES and the WEL are different in the clinical course, morphology and the histological picture, and considered to be of a different quality.
