Clinicopathological features of patients with acute graft‐versus‐host disease of the upper digestive tract

Abstract

Among the gastric endoscopic findings, mucosal exfoliation, although rare, and redness, luster, and mucosal change are likely to be useful diagnostic predictors of upper GI GVHD. GVHD was frequently diagnosed in patients with endoscopically normal duodenum, suggesting that biopsies are important for definitive diagnosis.
