回肠原发间变性大细胞淋巴瘤临床病理观察

目的：探讨回肠原发性间变性大细胞淋巴瘤（ALCL）的临床病理特点、免疫组化特征及预后。方法：运用组织形态及免疫组化方法研究1例发生在回肠的间变性大细胞淋巴瘤,并结合文献进行分析讨论。结果：间变性大细胞淋巴瘤其形态学表现为多样性,免疫组化显示CD30及CD45RO均为阳性,CK和EMA也可阳性。结论：间变性大细胞淋巴瘤发生在回肠非常罕见,其形态学和免疫表型有一定的特殊性,且预后良好,但要与其他类型淋巴瘤相鉴别。

Clinical pathological analysis of primary ileum anaplastic large cell lymphoma

Objective:To observe the clinicopathologic features,immunohistochemical features and prognosis of primary ileum anaplastic large cell lymphoma.Methods:A case of primary ileum anaplastic large cell lymphoma was studied by the means of histological observation and immunohistochemistry,and discussed with the related literatures.Results:Anaplastic large cell lymphoma displayed diversity in histology. The immunohistochemical results of CD30,CD45RO,CK and EMA were positive.Conclusion:The anaplastic large cell lymphoma occurring in the ileum is very rare. Its morphology and immunophenotype are special in some features. Furthermore,the favorable prognosis is gained. However,It differs from other types of lymphoma.
