Review of the diagnosis of gastrointestinal lanthanum deposition

Figure 5 Correlation between intestinal metaplasia and lanthanum deposition in the stomach. A: Esophagogastroduodenoscopy shows an annular whitish lesion in the gastric antrum (white light observation); B: Esophagogastroduodenoscopy shows an annular whitish lesion in the gastric antrum (narrow-band imaging); C, D: Biopsy sample acquired from a white lesion (A, B, arrows) contains intestinal metaplasia (C) and lanthanum deposition (D); E, F: In contrast, the sample acquired from the surrounding mucosa approximately 5 mm away from the white lesions (A, arrowhead) contains no intestinal metaplasia (E) and lanthanum deposition is subtle (F).
