Abstract

A 37-year-old woman was diagnosed by esophagogastroduodenoscopy (EGD) as having a 15-mm subepithelial lesion (SEL) in the gastric body. For 2 years, she experienced epigastric pain and anemia; she then underwent emergency EGD, which revealed a significant morphological change of the lesion. The SEL had a disintegrated tip and its submucosal portion was substantially exposed out of the mucosa, showing an “erect penis like appearance”. Based on the pathological findings of biopsied samples from the exposed portion and the endoscopic features, an inflammatory fibroid polyp (IFP) was suspected. This lesion was considered responsible for the anemia and was removed by endoscopic submucosal dissection (ESD). The pathological findings confirmed the lesion to be IFP. This report presents a case of gastric IFP that showed a marked morphological change and unique endoscopic features and was successfully removed by ESD.
