Inflammatory fibroid polyp (Vanek’s polyp): a case report and literature review

Article Type, Issue, Pathology, Vol 51, Issue 2 /

Célia S. J. Fazzio; Eveline B. MadeiraJ. Bras. Patol. Med. Lab. 2015;51(2):117-120DOI:10.5935/1676-2444.20150021 ABSTRACT Inflammatory fibroid polyp (IFP) is a benign uncommon lesion (1%-4% of gastric benign lesions), originated from the submucosa of the gastrointestinal tract. Its origin is controversial and immunohistochemical studies of lesions have largely refuted the possible vascular, neural or smooth muscle origin.
