Purpose To investigate the clinical features,pathological type and composition of nasal cavity and nasopharyngeal lymphoma.Methods The clinical data,histopathologic features and immunotypes of 319 consulted cases of nasal cavity and nasopharyngeal lymphoma from department of pathology,Beijing Friendship Hospital,Capital Medical University were retrospectively analyzed.According to the new WHO (2008) classification,all data of these cases were reappraised.Results Among these 319 cases,3 cases (0.9％) were diagnosed as classical Hodgkins lymphoma (CHL).Other 316 cases (99.1％) were diagnosed as non-Hodgkins lymphoma (NHL),56.0％ (177 cases) of them were T and NK-cell lymphoma and 44.0％ (139 cases) were B-cell lymphoma.The commonest subtypes were extra-nodal NK/T-cell lymphoma (NK/TCL) in 160 cases (50.6％),diffuse large B-cell lymphoma in 64 cases (DLBCL 20.3％).Among these 319 cases,106 cases (33.2％) over 60 years old were diagnosed as NHL.The most common subtypes were DLBCL in 40 cases (37.7％),NK/TCL in 36 cases (34.0％).There was no statistic difference in the incidence rate between the two types.Other 210 cases of NHL 0.9％ below 60 age including NK/TCL 124 cases (59.0％)and DLBCL 24 cases (11.4％).The diference is statistically significant.Conclusion Among those 319 nasopharyngeal lymphoma cases,3 cases are considered as CHL.NK/TCL is the commonest subtype of other 316 cases.DLBCL and NK/TCL are the most common subtypes in 106 cases over 60 years old.There was no statistic difference in the incidence rate between the two types.%目的 探讨鼻腔鼻咽部淋巴瘤的临床特点、病理分型及类型构成.方法 回顾性分析首都医科大学附属北京友谊医院病理科319例鼻腔鼻咽部淋巴瘤会诊病例的临床资料、病理组织学特征及免疫表型,按WHO(2008)分类标准进行病理诊断及分类,并对统计结果进行对比分析.结果 319例会诊病例中,3例(0.9％)诊断为霍奇金淋巴瘤混合细胞型,考虑肿瘤累及鼻咽,建议全身检查;316例均为非霍奇金淋巴瘤(99.1％),包含非霍奇金T和NK细胞起源淋巴瘤177例(56.0％)、B细胞起源淋巴瘤139例(44.0％).发病率位于前两位的是NK/T细胞淋巴瘤鼻型160例(50.6％)、弥漫大B细胞淋巴瘤64例(20.3％).NK/T细胞淋巴瘤发病率高于弥漫大B细胞淋巴瘤.≥60岁的患者106例(33.2％)诊断均为非霍奇金淋巴瘤,其中弥漫大B细胞淋巴瘤40例(37.7％)、NK/T细胞淋巴瘤36例(34.0％),弥漫大B细胞淋巴瘤与NK/T细胞淋巴瘤发病率无统计学意义.＜ 60岁的非霍奇金淋巴瘤患者210例(66.5％),其中NK/T细胞淋巴瘤124例(59.0％)、弥漫大B细胞淋巴瘤24例(11.4％),发病率差异有显著性.结论 316例鼻腔鼻咽部非霍奇金淋巴瘤中以NK/T细胞淋巴瘤最为多见,第二位是弥漫大B细胞淋巴瘤;≥60岁老人鼻腔鼻咽部淋巴瘤患者弥漫大B细胞淋巴瘤、NK/T细胞淋巴瘤最为多见,两者之间发病率差异无显著性.
