 To determine the endoscopic findings of amyloidosis of the small intestine, we reviewed 14 subjects with enteroscopically verified lesions. In 11 cases of AA amyloidosis, a mucosal pattern with innumerable fine granular elevations was evident, which correlated with expansion of the amyloid deposits in the lamina propria. In two patients with AL amyloidosis, there were polypoid protrusions and invariable thickening of the folds, which reflected massive amyloid deposits in the muscularis mucosa, submucosa, and muscularis propria. Three of five chronic NSAID users with AA amyloidosis had multiple mucosal defects in the ileum.
