Localized gastric amyloidosis: a case report.

Local deposition of amyloid without systemic involvement is rather uncommon and has been found in many organs. A 67-year- old man was admitted to our hospital presenting with weight loss, fatigue and poor appetite. Blood work and bone marrow examination revealed megaloblastic anemia. Upper gastrointestinal endoscopy reveeled e purple polypoid wass lesion of 5mm eliameter in the paracardiac region. Histopathologic examination of the gastric biopsy showed the deposition of amyloid materials in the mucosa. The patient had no evidence suggesting systemic amyloidosis. We report a rare case of localized amyloidosis of the stomach. The clinical and pathological features of this rare condition and association with megaloblastic anemia are discussed.
