We herein report an extremely rare case of localized gastric amyloidosis (LGA) with morphological changes during the follow-up. A 71-year-old woman who had a depressed lesion with central elevation in the gastric lower body was diagnosed with LGA. Esophagogastroduodenoscopy at 10 years after the initial examination showed that the lesion had grown and changed morphologically, exhibiting a submucosal tumorlike appearance. Since the lesion was confined to the submucosa, the patient underwent endoscopic submucosal dissection. The final pathological diagnosis was amyloid light-chain (AL)-type LGA. This case may provide useful information regarding the natural history of AL-type LGA.
