摘要

对1例鼻咽睾丸核蛋白(nuclear protein of the testis,NUT)癌的临床及病理特征进行回顾性分析,并结合文献复习。NUT癌镜下见条索状或巢片状生长的肿瘤细胞,其间见纤维黏液样间质,肿瘤细胞质呈淡嗜伊红色,细胞核增大,核形不规则,核染色质粗,部分细胞可见核仁,偶见核分裂象。免疫组织化学:NUT阳性,AE1/AE3,Syn,CgA,CD56有不同程度的表达,S-100,P63,前列腺特异抗原(prostate-specific antigen,PSA),前列腺特异抗原密度(prostate-specific antigen density,PSAD)均阴性。NUT癌是高度侵袭性肿瘤,病理学特征、免疫组织化学检查结果、NUT抗体是其重要的诊断依据。

Abstract

The clinical and pathological features of a case of nuclear protein of the testis (NUT) were analyzed and discussed in the literature. NUT carcinoma showed chord-like or nest-like tumor cells with fibromyxoid stroma between them. The cytoplasm of tumor cells was light eosinophilic, with enlarged nuclei, irregular nuclear shape, rough nuclear chromatin and some cells with nucleoli and occasional mitotic figures. Immunohistochemistry showed that NUT positive, AE1/AE3, SYN, CgA, CD56 had different degrees of expression, and S-100, P63, prostatespecific antigen (PSA), prostate specific antigen density (PSAD) were negative. NUT is a highly invasive tumor. Pathological features, immunohistochemistry and NUT antibodies are important diagnostic criteria.
