Glycogenic acanthosis of the esophagus is an uncommon benign change of the esophagus with a distinctive endoscopic appearance.

General

  • Uncommon - seen 3.5% of consecutive 2328 upper endoscopies.[1]
  • Benign.[2]
  • May be associated with GERD;[1] however, lesions do not resolve with PPI treatment.[2]
  • Possible association with ingestion of hot liquids.[3]

Gross/endoscopic

  • Distinctive endoscopic appearance - grey/white raised lesion.[3]
