Gong and Bang: Whitish gastric mucosa on upper gastrointestinal endoscopy

Quiz

A 60-year-old man with hypertension and chronic glomerulonephritis visited the gastroenterology department for upper gastrointestinal endoscopy. He has been undergoing continuous ambulatory peritoneal dialysis for the past 8 years. He denied having any symptoms, and the vital signs were normal. On laboratory tests, the serum levels of hemoglobin, calcium, phosphorus, blood urea nitrogen, and creatinine were 9.8 g/dL, 9.5 mg/dL, 4.9 mg/dL, 71.3 mg/dL, and 11.8 mg/dL, respectively. His current medications are olmesartan, felodipine, lanthanum carbonate, calcitriol, cinacalcet hydrochloride, atorvastatin, darbepoetin alfa, and multi-vitamins. Endoscopy revealed diffuse whitish granular mucosa on the greater curvature side, posterior wall of the high body, and cardia (Fig. 1AD). The patient had no Helicobacter pylori infection.
What is the most likely diagnosis?
