Methods: The clinical symptoms, histopathologic features and immunohistochemical (ABC method) staining in 9 cases were observed. Results: IFP presented either as a solitary pedunculated or sessile lesion arising from the submucosa and protroding into the lumen; composed of a background of fibroblasts and blood vessels infiltrated by a variable number of inflammatory cells, often numerous eosinophilias leukocytes. Immunohistochemical staining: the spindle cells of all cases reacted with Vimentin. The partial cells of several cases react with Actin, NSE, a -AT. 7 cases were follow-up. No patients had a recurrence of the lesion. Conclusion: IFP are rare lesions, and may represent an exaggerated response to inflammatory or other injury process. The prognosis is good when treated by segmental resections of endoscopic removals.展开更多

We report a case of computed tomography(CT) imaging finding of a gastric IFP with massive fibrosis. CT scans showed thickening of submucosal layer with overlying mucosal hyperenhancement in the gastric antrum. The submucosal layer showed increased enhancement on delayed phase imaging. An antrectomy with gastroduodenostomy was performed because gastric cancer was suspected, particularly signet ring cell carcinoma. The histopathological diagnosis was an IFP with massive fibrosis. The authors suggest that when the submucosal layer of the gastric wall is markedly thickened with delayed enhancement and preservation of the mucosal layer, an IFP with massive fibrosis should be considered in the differential diagnosis.展开更多

The clinical presentation depends on the size and localization. They are particularly found in the ileum, where they are frequently present as an ileal intussusception. We report the case of a 56-year-old female patient who presented with periumbilical pain along with multiple episodes of vomiting and chronic constipation. An abdominal CT scan revealed an ileo-ileal intussusception of an endoluminal hypodense lesion with mesenteric lymphadenopathy. Surgical treatment consisted of segmental ileal resection with primary anastomosis. The histopathological analysis revealed an inflammatory fibroid polyp in the ileum. Although these tumors have no malignant potential, surgery is always indicated in ileo-ileal intussusception to ascertain the histological nature of the lesion.展开更多
