【摘要】 目的 探讨炎症性肌纤维母细胞瘤(IMT)的临床病理特征、鉴别诊断。方法 分析4例IMT患者的临床病理资料，进行光镜观察，免疫组化染色，并复习文献。结果 肿瘤由梭形细胞、大量慢性炎性细胞及黏液血管样背景构成。肿瘤细胞表达Vimentin、SMA、MSA、Desmin。随访5～54个月，均未见肿瘤复发和转移。结论 IMT是以炎症为背景、肌纤维母细胞增生为主的一种少见的良性肿瘤，少数具有复发倾向及恶变潜能。确诊依靠病理，应注意与一些软组织肿瘤和瘤样病变鉴别。

    【Abstract】 Objective To investigate the clinicopathological characteristics and differential diagnosis of inflammatory myofibroblastic tumors(IMT).Methods Four cases of IMT were investigated at the light microscopic level and were studied by immunohistochemical techniques，and the literatures were reviewed. Results The tumor consisted of spindle cells，large number of chronic inflammatory cells and myxoid background with delicate vasculature. Tumor cells expressed vimentin，SMA，MSA，Desmin. No patient had recurrence and metastasis of the tumor during the followinging 5～54 months.Conclusion IMT is a kind of rare benign tumor which takes inflammation as background and myofibroblastic hyperplasia as main pathological changes ......
