消化道炎性纤维性息肉14例临床病理分析

Inflammatory fibroid polyps in digestive tract: a clinical and pathological analysis of 14 cases

目的探讨消化道炎性纤维性息肉(inflammatory fibroid polyps,IFPs)的临床病理学特征、诊断、鉴别诊断及临床治疗。方法回顾性分析14例消化道IFPs的临床病理学特征并复习相关文献。结果 14例IFPs中大体表现多为黏膜下息肉样或半球形隆起性肿物,光镜下以增生的梭形纤维细胞围绕血管形成"洋葱皮样"外观及间质较多嗜酸性粒细胞浸润为主要组织学特征,免疫组化标记肿瘤细胞表达纤维和肌纤维母细胞及树突细胞表型。结论 IFPs是消化道少见的良性间叶性肿瘤,具有独特的病理组织学改变,手术或内镜下肿物完整切除是主要的治疗方法。

Purpose To investigate the clinical and pathological features of inflammatory fibroid polyps （ IFPs） and to discuss its diag-nosis, differential diagnosis and treatment. Methods Clinicopathological data of 14 cases of IFPs were collected and analyzed retro-spectively. Results Most of the 14 cases were found to have submucosal polyps of the digestive tract protruding growing into the cavi-ty. Perivascular onion skinning which formed by spindle fibrocytes around vascular proliferation and eosinophilic inflammatory infiltrates were present as the characteristic feature of lesions. ABC results demonstrated that the lesions showed fibroblastic, myofibroblastic and dendritic cell signs. Conclusions IFPs are rare, benign tumors that can arise throughout the digestive tract, with unique histological changes in pathology. Surgical excision or endoscopic removal is the main treatment.
