Title: Invasive inflammatory fibroid polyp of the stomach: a case report and literature review. Author: Harima H, Kimura T, Hamabe K, Hisano F, Matsuzaki Y, Sanuki K, Itoh T, Tada K, Sakaida I. Journal: BMC Gastroenterol; 2018 May 31; 18(1):74. PubMed ID: 29855265. Abstract: BACKGROUND: Inflammatory fibroid polyps (IFPs) are rare mesenchymal lesions that affect the gastrointestinal tract. IFPs are generally considered benign, noninvasive lesions; however, we report a case of an invasive gastric IFP. To the best of our knowledge, this is only the second case report of an invasive gastric IFP. CASE PRESENTATION: A 62-year-old woman presented with complaints of epigastric pain and vomiting. Computed tomography showed a 27-mm, hyper-enhancing tumor in the prepyloric antrum. Upper endoscopy also showed a submucosal tumor causing subtotal obstruction of the gastric outlet. Because a gastrointestinal stromal tumor was suspected, distal gastrectomy was performed. Histopathological examination revealed spindle cell proliferation in the submucosal layer. The spindle cells had invaded the muscularis propria layer and extended to the subserosal layer. The tumor was finally diagnosed as an IFP based on immunohistochemical findings. No mutations were identified in the platelet-derived growth factor receptor alpha (PDGFRA) gene via molecular genetic analysis. DISCUSSION AND CONCLUSIONS: After the discovery that IFPs often harbor PDGFRA mutations, these growths have been considered neoplastic lesions rather than reactive lesions. Based on the present case, IFPs might be considered not only neoplastic but also potentially invasive lesions.[Abstract] [Full Text] [Related] [New Search]
