目的 探讨结节性淋巴细胞为主型霍奇金淋巴瘤 (NLPHL)的诊断和鉴别诊断特点。方法 对 1980～ 2 0 0 0年 2 4 5例霍奇金淋巴瘤 (HL)进行回顾性分析 ,发现NLPHL4例 ;另外 2例NLPHL为 2 0 0 0年会诊病例 ;复旦大学肿瘤医院提供 1例。 7例均应用链霉菌抗生物素蛋白 过氧化物酶法(SP法 )检测瘤细胞 (CD4 5、CD2 0、CD15、CD30、波形蛋白 )和背景细胞 (CD3、CD2 0、CD4 5RO、CD5 7、CD6 8、TIA 1)的免疫表型 ,并采用WHO1997年淋巴瘤诊断标准重新分类。结果 NLPHL7例 ,男 4例 ,女 3例 ,平均年龄 4 3.8岁 ,中位年龄 4 3岁 ,表现为颈部、锁骨上或腋窝淋巴结肿大 ,临床Ⅰ期。组织学上 ,NLPHL病变淋巴结结构破坏 ,大部分为肿瘤性病变 ,主要呈结节性生长 ,结节内可见L&H细胞浸润 ,其中 1例NLPHL病变淋巴结可见少部分呈生发中心进行性转化 (PTGCs)改变。免疫组织化学染色显示瘤细胞呈CD4 5、CD2 0阳性 ,CD15、CD30、波形蛋白阴性 ,背景细胞中可见大量CD2 0阳性的B小淋巴细胞及较多CD5 7阳性细胞 ,TIA 1阳性细胞极少见。结论 对NLPHL的诊断必需结合免疫表型特征 。
Objective To study the diagnosis and the differential diagnosis of nodular lymphocyte predominant Hodgkin′s lymphoma (NLPHL). Methods 245 cases of Hodgkin′s lymphoma (HL) diagnosed between 1980 and 2000 from 3 hospitals in Guangzhou were reviewed. Four cases of NLPHL were confirmed according to the WHO classification of lymphoid neoplasms. Among the other 3 cases of NLPHL, 2 collected from other clinical centers and 1 from Fudan University Cancer Hospital. Immunohistochemistry (IHC) were performed on paraffin sections through SP technique using a panel of markers to define the large neoplastic cells (CD45, CD20, CD15, CD30 and vimentin) as well as the non neoplastic background cells (CD3, CD20, CD45RO, CD57, CD68 and TIA 1). Results Seven patients with NLPHL were 4 males and 3 females, age 29 to 70 years, average 43 8 years. All patients had lymphadenopathy. Histologically, in NLPHL, instead of the structure of normal lymph nodes, the tumor tissue became nodular in architecture. Characteristic lymphocytic and histiocytic (L&H) cells with scant cytoplasm and large multilobulated nuclei distributed among a predominant population of small lymphoid cells. The large cells exhibited a CD45+, CD20+, but CD15-, CD30- and vimentin phenotype. The background cellularity was relatively rich in B cells and the majority of T cells infiltrated were CD57 + cells. TIA 1+ cells were few. Conclusions NLPHL can be diagnosed according to the morphologic and immunophenotypic features rather than by morphology alone. It is important to distinguish this tumor from its morphologic mimics, such as lymphocyte rich classical Hodgkin′s lymphoma (LRCHL) and T cell rich B cell lymphoma (TCRBCL). The immunophenotype of neoplastic cells and background cells are the helpful criteria for the differential diagnosis.
