Whitish gastric mucosa on upper gastrointestinal endoscopy.

This article, published in Clinical Endoscopy, discusses the case of a 60-year-old man who underwent an upper gastrointestinal endoscopy. The endoscopy revealed whitish granular mucosa on the greater curvature side, posterior wall of the high body, and cardia of the stomach. The patient had been undergoing continuous ambulatory peritoneal dialysis for 8 years and was taking various medications. The most likely diagnosis was gastric lanthanum carbonate deposition, which is a known side effect of lanthanum carbonate, a medication used to treat hyperphosphatemia in patients with end-stage renal disease. The article emphasizes the importance of histopathological examination and a detailed medical history for a definitive diagnosis. It also states that gastric lanthanum deposition is generally considered safe and does not cause clinical symptoms. [Extracted from the article]
