Unexpected CA19‑9-producing esophageal submucosal gland duct adenoma with high-grade dysplasia：A case report and review of literature

2026-08-31

Abstract excerpt

<title>Abstract</title> <p> <bold>BACKGROUND</bold> Esophageal submucosal gland duct adenoma (ESGDA) is a rare tumor that originates from clusters of esophageal submucosal gland ducts. Although ESGDA is generally classified as benign, research on its association with high-grade dysplasia and specific tumor markers, such as CA19-9 expression, remains insufficient. Herein, we present the rare case in the literatu...
