Esophagogastroduodenoscopy (EGD) showed a benign-appearing stenosis with a single 7-mm nodule at the gastroesophageal junction and non-bleeding gastric ulcers in the setting of residual food in the stomach (Figure 1).
Hematoxylin and eosin stain (magnification 600x). (A) Esophageal and (B) gastric biopsy showing purple Sarcina ventriculi cocci in characteristic tetrads (long arrows) that are larger in comparison to the luminal bacilli (arrowheads). There is mild acute inflammation demonstrated by the intraepithelial neutrophils (short arrows), in the adjacent gastric epithelium.
