What Is Glycogenic Acanthosis?

Glycogenic acanthosis is a benign thickening of the esophageal squamous epithelium (surface cell lining)  characterized by the presence of numerous, uniformly grey-white plaques made up of large squamous cells filled with glycogen.

The wax-like plaques in glycogenic acanthosis are usually 2-10 mm in diameter and may be confluent round elevations involving the entire esophageal surface.¹

On x-ray  views of the well-distended esophagus, the plaques appear as a finely nodular or cobblestone mucosal pattern.

The findings are not associated with mucosal ulcerations, luminal narrowing, or mobility disturbance, although some patients may have coexistent hiatal hernia and gastroesophageal reflux.²
