Esophagus web
  • Uncommon, semi circumferential mucosal protrusions
  • Most commonly in upper esophagus in women over 40
  • Episodic dysphagia associated with "bolting" solid food
  • Vascularized fibrous tissue covered by squamous mucosa
  • Treatment: myomectomy, dilation
  • Plummer-Vinson syndrome: Triad of dysphagia, iron-deficiency anemia, and esophagus web, higher risk for esophagus squamous cell carcinoma
Esophagus ring
  • Concentric, smooth protrusions of normal esophageal tissue (mucosa, submucosa and muscularis propria) into the lumen
  • Usually in distal esophagus
  • Congenital or scar from caustic liquids
  • Type A: Lower muscular ring; thickened circular smooth muscle with overlying squamous mucosa
  • Type B: Lower mucosal ring/Schatzki’s ring; lined by squamous epithelium and columnar-type epithelium; ring contains connective tissue and fibers of muscularis mucosae
