Glycogenic acanthosis of the esophagus, abbreviated GAE, 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][3] however, lesions do not resolve with PPI treatment.[2]
- Possible association with ingestion of hot liquids.[4]
- Described in the context of Cowden's disease when seen diffusely.[5]
Gross/endoscopic
- Distinctive endoscopic appearance - grey/white raised lesion.[4]
