Microscopic (histologic) description
  • Most common upper GI inflammatory pattern is focal gastritis, followed by gastric basal mixed inflammation and superficial plasmacytosis (Am J Surg Pathol 2010;34:1672)
  • Variable changes include multiple tiny shallow ulcers, crypt abscess formation, increased intraepithelial lymphocytes, villous blunting
  • Microscopic findings parallel remissions and relapses of colonic inflammation
