A case of endoscopic ultrasound diagnosis of gastric amyloidosis.

A 37-year-old female presented to our hospital with the complaint of abdominal distension for one month. A gastroscopy examination showed extensive chyme retention and varying erosion and ulceration of the gastric body. The pathology showed moderate chronic inflammation and erosion of the gastric body mucosa, with accompanying Helicobacter pylori infection. She accepted treatment for one month. The patient then accepted to undergo endoscopic ultrasonography, which showed that normal structure of the gastric body intumescence was discernible. The pathology showed chronic mild-moderate inflammation of the gastric body mucosa associated with interstitial amyloidosis, with accompanying Helicobacter pylori infection. She accepted treatment for the eradication of Helicobacter pylori, and the original ulcer healed.
