Gastric pseudotumoral lesion caused by a fish bone mimicking a gastric submucosal tumor

Abstract

Gastric complications following unintentional foreign body ingestion are extremely rare. Here, we report the case of a 59-year-old healthy woman who presented with nonspecific abdominal pain and an apparent gastric submucosal tumor that was incidentally detected by gastrofiberscopy. The patient underwent laparoscopic surgery, which revealed an intact gastric wall with no tumor invasion, deformity, or evidence of a gastric submucosal lesion. However, an impacted fish bone was found.
