Definition / general
  • Also called mucocele
  • Derive from obstructed submucosal gland ducts
  • Small, usually in lower esophagus
  • May cause intramural pseudodiverticulosis, with multiple flask-like invaginations into esophageal wall (Am J Clin Pathol 1976;65:314)
  • Associated with chronic esophagitis and fibrosis; also surgically isolated segments of esophagus (Dis Esophagus 2002;15:96)
Microscopic (histologic) description
  • Saccular or flask shaped dilation of submucosal gland excretory ducts; rarely reaches muscularis propria
  • In large lesions, muscularis does not accompany the lesion so are not true diverticula
