title: Inflammatory fibroid polyp associated with early gastric carcinoma: a case report.
abstract: Inflammatory fibroid polyp (IFP) is a rare mesenchymal lesion of the gastrointestinal tract. The association of IFP with gastric carcinoma has been only reported in 7 previously published cases. We present the case of a 69-year-old man who underwent gastrectomy because of an early gastric carcinoma invading the submucosa with an underlying IFP, which pushed the neoplastic surface to the gastric lumen in a polypoid fashion. The IFP revealed a CD34-positive spindle cell proliferation surrounding blood vessels in a concentric way and covered by carcinomatous glands. The patient is free of disease after 108 months of follow-up. The underlying spindle cell proliferation and blood vessels may be reactive to malignant glands found in the surface, although recent molecular analyses support the neoplastic nature of this lesion.
