{Abstract}: Inflammatory myofibroblastic tumors (IMTs) are mesenchymal tumors of intermediate malignant potential. Gastric IMTs are rare and commonly affect young adults. They are typically confused with gastrointestinal stromal tumors, inflammatory fibroid polyps, and leiomyosarcomas. The etiology of IMTs remains unclear, but is theorized to be due to hyperinflammatory response to chronic infections. We present a middle-aged woman found to have a gastric mass positive for Helicobacter pylori, underwent multiple endoscopies with endoscopic ultrasound, and a definitive diagnosis of gastric IMT was only made after a partial gastrectomy with immunohistochemistry negative for CD-117, S-100, ALK-1, and positive for vimentin and SMA.
