In primary amyloïdosis (light chain amyloïdosis), localized gastric involvement is a rare finding which can mimick malignancy. We report the case of a 75-year-old woman, admitted with upper digestive outlet obstruction and generalized edema. Upper endoscopy revealed fundic burgeoning ulcerative process. Gastric biopsy concluded to AL type amyloidosis and no malignant tumor was found. Etiological treatment consisted of melphalan and prednisone every 6 weeks. The patient improved from her gastric complaints, and edema. The current decline is 24 months. http://pubs.sciepub.com/ajmcr/3/2/8/ajmcr-3-2-8.pdf Amyloidosis stomach cancer
