摘要 目的:探讨鼻咽部低级别乳头状腺癌( low grade naso-pharyngeal papillary adenocarcinoma, LGNPPA)的临床病理学特征。方法回顾性分析2例LGNPPA的临床病理学及免疫表型特征,并复习相关文献。结果2例均为男性,年龄分别为36岁和25岁。镜下见肿瘤细胞围绕纤维血管轴心排列成乳头状结构,呈外生性或内翻性生长,外生性有分支,部分排列成腺样结构,肿瘤细胞呈立方状或假复层柱状,胞质中等丰富,嗜酸性,部分呈梭形,束状排列,细胞核无明显异型性及核分裂象,未见坏死。免疫表型:肿瘤细胞强阳性表达CKpan(2/2)、CKH (1/1)、CK7(1/1)、TTF-1(2/2),中等强度表达EMA (2/2)、vimentin (1/1),弱阳性表达CD117(1/1)、p63(1/1),Ki-67增殖指数5%~50%,均不表达Tg、S-100蛋白、desmin、SMA、Syn、CgA、CD56、CD34、Calponin、CK20、Neu-N、GFAP、Olig-2。 EBER原位杂交检测阴性。结论 LGNPPA是一种罕见的鼻咽上皮来源的低度恶性肿瘤,具有典型的形态学特征,该肿瘤易与转移性甲状腺乳头状癌、鼻咽部多形性低度恶性腺癌等混淆,其诊断及鉴别诊断主要依靠病理形态学和免疫表型。
