67例面中线非霍奇金淋巴瘤临床病理及其EBV感染关系

The Clinicopathology of Non-Hodgkin 's Lymphoma in the Midline and Its Relationship with Epstein-Barr Virus Infection

老年组面中线非霍奇金淋巴瘤多发生在扁桃体和鼻咽部，组织学类型以低度恶性黏膜相关淋巴组织淋巴瘤（MALT）为主；

The lesions of elderly patients group were located in tonsil and nasopharynx . Most of them were mucosa associated lymphoid tissue lymphoma ( MALT );

结论面中线NHL以NK/T细胞淋巴瘤多发，EBV感染与淋巴瘤组织类型有关，与部位无关。

Conclusion The lymphomas of the midline are more often occurred as NK / T cell lymphomas , the infection of EBV has a relationship with the histology type of lymphomas , not with the site .

目的以非老年组（年龄<60岁）面中线非霍奇金淋巴瘤患者为对照，探讨老年组（年龄≥60岁）面中线非霍奇金淋巴瘤的临床病理、免疫表型及EB病毒（EBV）感染状态。

Objective To study clinicopathological , immune marker and EBV infection of elderly patients group (≥ 60 years ) with non-Hodgkin 's lymphoma ( NHL ) of the midline , in comparison with non-old patients group ( < 60 years ) with the same malignant lymphoma .

结果（1）67例面中线非霍奇金淋巴瘤中老年组31例，占46.3%；非老年组36例，占53.7%。

Results ( 1 ) In 67 cases of NHL of the midline , there were 31 cases in elderly patients group ( 46.3 % ) and 36 cases in non-old patients group ( 53.7 % );
