前言目的分析淋巴结外非霍奇金淋巴瘤（NHL）的临床表现特点及误诊原因。方法回顾性分析127例原发结外非霍奇金淋巴瘤的发病情况、原发部位分布情况、首发症状及误诊情况等。结果原发于结外的非霍奇金淋巴瘤127例,占同期非霍奇金淋巴瘤53.81%（127/236）;原发部位前5位依次为:胃肠道21.26%（27/127）,鼻腔18.9%（24/127）,Waldeyer环14.96%（19/127）,脾脏12.6%（16/127）,皮肤6.3%（8/127）;结外奇非霍金淋巴瘤误诊率为69.29%（88/127）;结外非霍奇金淋巴瘤首发症状因原发部位不同而临床表现各异,无特异性。结论结外NHL发生率较高,其临床表现缺乏特异性,早期易误诊。
