A 73-year-old man presented for upper endoscopy due to right upper quadrant pain that was subsequently diagnosed as myofascial pain. Incidentally, endoscopy demonstrated a 3-cm antral submucosal tumour with a sub-centimeter satellite nodule (Figure 1A and andB).B). The patient subsequently had endoscopic ultrasound + fine needle aspiration that demonstrated a hypoechoic lesion arising from the muscularis mucosa. Fine needle aspiration was non-diagnostic. Considering that the lesion met size criteria, a plan for resection was made. Given the unknown pathology, the lesion was excised via endoscopic submucosal dissection to ensure an R0 resection. Final pathology demonstrated an inflammatory fibroid polyp (Figure 1D–F). Inflammatory fibroid polyps are rare gastric lesions that makeup ~0.1% of encountered gastric polyps (1). These are usually incidental findings on upper endoscopy. However, they can result in bleeding, gastric outlet obstruction, epigastric pain or recurrent nausea, and vomiting (2,3). Although rare, IFPs should be included in the differential for gastric submucosal tumours.
