A 56-year-old female with epigastralgia, was diagnosed with submucosal tumor with ulceration in the antrum of the stomach by endoscopy. Although the diagnosis was submucosal tumor, due to her continuing symptoms, we treated her with H2-receptor antagonist. This treatment was not effective. Therefore, the tumor was surgically removed. Histologically, her gastric tumor was diagnosed as inflammatory fibroid polyp (IFP) . Gastric IFP is rare, and it is very difficult to differentiate between IFP and other submucosal tumors.
We reported a case of gastric IFP, that showed the same symptoms as gastric ulcer.
