“…This may be due to the presence of amyloid deposits without a cell component. Indeed, this finding differs from the typical EUS findings of gastric cancer (hypoechoic) (22) or malignant lymphoma (hypoechoic or very hypoechoic) (23). Although further studies will be required to reach a definitive conclusion, this finding may be helpful for diagnosing amyloidosis.…”

Localized Gastric Amyloidosis that Displayed Morphological Changes over 10 Years of Observation

et al. 2021

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.
