Glycogenic acanthosis of the esophagus
Diagnosis in short

Glycogenic acanthosis of the esophagus. H&E stain.
LM squamous epithelium with (1) superficial clearing of the cytoplasm, and (2) thickening
Site esophagus
Associated Dx possibly associated with gastroesophageal reflux disease
Syndromes possibly Cowden's disease when diffuse
Clinical history ingestion of hot liquids (???)
Prevalence uncommon
Endoscopy raised grey/white lesions
Prognosis benign

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]
