Definition / general
  • Cannot definitely diagnose on biopsy, need resection specimen; however, can suggest diagnosis with appropriate findings
  • Associated with GI Crohn's disease; esophageal involvement in 0.2 - 13% with ileocolic Crohn's disease
  • Usually extraesophageal Crohn's disease at time of presentation in esophagus (Inflamm Bowel Dis 2001;7:113)
  • Isolated esophageal involvement is extremely rare; when first diagnosed in esophagus, intestinal involvement usually follows
  • Clinical and endoscopic appearances are highly variable and may not correlate (J Pediatr Gastroenterol Nutr 2003;36:454)
