Primary gastric lymphoma, an uncommon gastric tumor caused by infection with Helicobacter pylori, is rarely associated with gastric amyloidosis. Chronic bacterial infection is known to cause amyloidosis. We report a 53-year-old man who had an antral and duodenal mass with narrowing and ulceration on endoscopy and CT scan; endoscopic biopsy revealed gastric amyloidosis. Rapid urease test and serology for H. pylori were positive. Histology of resected specimen of distal stomach revealed primary gastric lymphoma, amyloid deposits and spiral organisms suggestive of H. pylori. Rectal biopsy was negative for amyloid. He remained well on follow-up after surgery and eradication of H. pylori.
