目的掌握胃肠道炎性纤维性息肉（ＩＦＰ）的诊断和鉴别诊断。方法观察９例ＩＦＰ临床、病理改变及免疫组织化学（ＡＢＣ）标记。结果ＩＦＰ是发生在胃肠道粘膜下，向腔内突出的息肉样肿块。以纤维血管增生伴数量不等的炎症细胞，特别是嗜酸性粒细胞浸润，纤维母细胞略呈车辐状排列，可围绕血管呈葱皮样改变为其组织学特征。免疫组织化学标记表达Ｖｉｍｅｎｔｉｎ（９／９），ＳＭＡ（６／９）。结论ＩＦＰ可能是对感染或其它原因损伤的过度反应，节段切除、内窥镜下摘除预后良好。
Objective To master the diagnosis and differential diagnosis of inflammatory fibrous polyposis (IFP) in the gastrointestinal tract. Methods The clinical, pathological changes and immunohistochemistry (ABC) markers of 9 cases of IFP were observed. Results IFP is a polypoid mass that protrudes from the gastrointestinal mucosa and protrudes into the lumen. Fibroblast proliferation with varying amounts of inflammatory cells, especially eosinophil infiltration, fibroblasts arranged slightly in a car-like arrangement, can be changed to histological characteristics around the blood vessels onion. Immunohistochemical markers express Vimentin (9/9), SMA (6/9). Conclusions IFP may be an overreaction to infection or other causes of injury. Segmental resection and endoscopic removal have a good prognosis.
