<unk>  stricture is the result of lower pressure of<unk>  sphincter in gastroesophageal reflux disease,<unk>  motor disorder, and inflammation and fibrosis in neoplasia. The characteristic findings on gross pathology are thickening of the lower<unk>  wall in gastroesophageal reflux disease, pale mucosa in lymphocytic esophagitis, and hemorrhagic congestion in caustic ingestion. Characteristic histopathological findings of<unk>  stricture are intraepithelial lymphocytosis and basal cell hyperplasia in gastroesophageal reflux disease; T lymphocyte infiltration in squamous mucosa in lymphocytic esophagitis and eosinophilic necrosis in caustic ingestion.
