Abstract
本文报道1例原发中耳DEK::AFF2融合阳性非角化型鳞状细胞癌(nonkeratinizing squamous cell carcinoma,NKSCC)。患者女,66岁,右耳疼痛、听力渐进性下降1年余。分别取中耳和鼻咽部两处标本送检,肿瘤细胞均呈乳头状瘤样生长,部分合并内翻性生长,细胞呈非角化型鳞状上皮形态,轻-中度异型,上皮及间质内富于炎性细胞,仅局灶呈浸润性生长。免疫组织化学肿瘤细胞表达细胞角蛋白(CK)5/6、p40、AFF2。荧光原位杂交检测DEK基因断裂重排,逆转录-聚合酶链反应及Sanger测序结果示DEK::AFF2基因融合。分子病理的检测有助于正确诊断。.
