Glycogenic acanthosis of the esophagus is a common benign entity, characterized by multifocal plaques of hyperplastic squamous epithelium with abundant intracellular glycogen deposits. Typically patients are asymptomatic. Knowledge of the nature, significance, and prevalence of esophageal mucosal plaques is limited. Common endoscopic finding (25%), often in lower esophagus ( Wikipedia: Glycogenic Acanthosis [Accessed 15 February 2019] ) Extensive glycogenic acanthosis may be associated with Cowden syndrome or tuberous sclerosis ( Am J Gastroenterol 1997;92:1038) but otherwise no clinical significance. 6, Iss: 04, pp 214-217 Out of 5000 consecutive double-contrast examinations of the esophagus, 50 cases presented a diffuse finely granular or nodular appearance of the mucosa. 1981; Glick et al.
