Abstract
White globe appearance has recently been identified as a novel endoscopic marker useful in the diagnosis of early gastric cancer. Recently, this lesion has also been reported in the noncancerous stomach, including cases with autoimmune atrophic gastritis, although the clinical significance remains unclear. We present the details of a 68-year-old woman who began vonoprazan therapy for severe gastroesophageal reflux disease causing esophageal stricture. On follow-up endoscopy 1 year after beginning vonoprazan, multiple white globe appearance lesions developed in all sections of her stomach, except for the antrum. We also detected lesions during a yearly follow-up in the noncancerous stomach of a 70-year-old man who had received vonoprazan for 3 years. Lesions in both cases constituted cystic gland dilatations containing eosinophilic material. There was no evidence of accompanying autoimmune atrophic gastritis in either patient. This report is the first to our knowledge describing newly developed white globe appearance lesions in the noncancerous stomach during follow-up in two cases who received vonoprazan. Our findings suggest that these lesions in the noncancerous stomach might be associated with vonoprazan treatment. We investigated the two cases endoscopically and histologically, and we report our findings with a literature review.
