Intermittent subobstruction and cholestasis as complications of duodenal amyloid tumours

Amyloidosis confined to the duodenum is uncommon. In the present report the history of an 83-year old patient, admitted for vomiting and heavy epigastric pain, is described. Radiographic and endoscopic investigation revealed two polypoid lesions in the duodenum (D2). Biopsies showed diffuse amyloid deposition in the lamina propria, muscularis mucosae and submucosa of the duodenum as well as vascular deposits. No other localisations were documented. Amyloid tumours of the gastrointestinal tract are rare but may lead to serious symptoms.
