She underwent esophagogastroduodenoscopy (EGD) with random gastric biopsies showing grossly normal mucosa, was consistent with chronic inflammation and focal foveolar hyperplasia, and negative for Helicobacter pylori (Figure 1). In general practice gastric biopsy specimens are often numerically and topographically inadequate for the evaluation of atrophic gastritis; therefore, we have included an algorithm to address specifically the steps that should be taken when confronted with suboptimal sampling. In such cases, immunostaining positive for prostate-specific antigen and cytokeratin, and negative for chromogranin suggests the diagnosis. 2018 Aug. Vinik AI, Chaya C.
