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
Stains PAS +ve, PASD -ve
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]
