Inflammatory fibroid polyp. A case report and review of the literature

Ann Ital Chir. Jul-Aug 2012;83(4):347-51.


Introduction: The Inflammatory fibroid polyp (IFP) is a mesenchymal polypoid lesion of the gastrointestinal tract that follows a benign course. Incidence is extremely low: from 0,1% to 2 %. Histologically, it consists of a sub mucous proliferation of vascolarized fibromuscolar tissue with a high eosinophils inflammatory infiltration. IFP can arise everywhere in the gastrointestinal tract but is described more frequently in the gastric antrum (70%).

Case report: We report a case of a 71-year-old woman presented to our department with a worsening history of lack's appetite, nausea and early satiety. We performed a review of the literature from 1949 to 2011. 196 cases of IFPs were found.

Conclusion: Clinical symptoms are heterogeneous and endoscopy's examination revealed only presence of a sub-mucosal lesion, and their biopsies often gave not diagnostic localization. In the differential diagnosis, it's important to discern between eosinophilic gastroenteritis, gastrointestinal stromal tumor, inflammatory pseudotumor, hemangioendothelioma, and hemangiopericytoma. Eco-endoscopic appearance and biopsies associated may provide useful informations, that can steer to the diagnostic suspect of IFP. Despite this is a benign lesion, this one often needs a surgical excision on healthy margin. In literature is also described high local recurrence, specially when incomplete excision proceeded.
