Differentiation of histomorphological features in squamous epithelium between pill-induced esophagitis and reflux esophagitis groups.

Each digit represents the number of cases showing those features in squamous epithelium.agrade 1, 1~ 9 eosinophils; grade 2, 10~29; grade 3, 30~59.bmild, 25~50% of total epithelial thickness; marked, >50%.cThe first represents P value between total cases of pill-induced esophagitis group and reflux esophagitis group, and the second denotes P value between in distal esophagus lesion of both groups.dNS, not significant.Differentiation of histomorphological features in squamous epithelium between pill-induced esophagitis and reflux esophagitis groups.
