摘要：肺淋巴上皮瘤样癌（lymphoepithelioma-like carcinoma，LELC）是一种少见的EB病毒（Epstein-Barr virus，EBV）相关性癌。其组织学特征是合体样生长方式伴有明显的淋巴细胞浸润，在组织学上与未分化鼻咽癌无法区分。然而，已有研究发现，LELC可以表现为非经典形态并缺乏显著的淋巴细胞浸润。本研究中，我们对61例肺LELC患者进行了系统的临床病理分析，并使用IHC分析软件对淋巴细胞浸润进行自动定量分析。结果表明，肺LELC具有形态学上的连续性，从具有高密度淋巴细胞浸润的经典低分化肿瘤形态，到几乎没有淋巴细胞浸润的非经典形态。这些EBV相关性肿瘤代表了一类特殊疾病，通常发生于女性和非吸烟患者。低密度淋巴细胞浸润的肿瘤与非角化性鳞状细胞癌非常相似，通常瘤体较大、在影像学上具有更高的最大标准化摄取值，且复发时间短于具有高密度淋巴细胞浸润的肿瘤。通过细致的病理检查，我们观察到一些肺LELC独特的形态学特征，包括肉芽肿性炎、局灶角化、肺泡腔播散及附壁样播散方式。我们还发现，表现为肉芽肿性炎的肿瘤患者预后较好；但是，是否存在肺泡腔播散与预后没有显著相关性。由于这些“LELC”与未分化鼻咽癌或淋巴上皮癌不同，我们建议使用另一个术语，EBV相关性肺癌，以涵盖这一特殊疾病的全部形态谱系。
