摘要
目的:研究原始性神经外胚层肿瘤(PNET)的特征。方法:采用光镜、电镜和免疫组化对1例颈部原始性神经外胚层肿瘤(PNET)进行观察。结果:肿瘤组织由小圆形细胞构成,肿瘤细胞胞膜示MIC2强阳性,肿瘤细胞胞浆内含有微管及神经内分泌颗粒。结论:PNET是一种极度恶性的软组织小圆形细胞肿瘤,它的诊断必须依靠免疫组化及电镜。
Purpose To study the features of primitive neuroectodermal tumor. Methods A case of PNET was observed by light microscopy, electric microscopy and immunohistochemistry. Results PNET was composed of small round cells. Tumor cell membrane was positive for MIC2 antibody. Under electric microscopy, neuroendocrine granules and microtubules were noted in the tumor cell plasma. Conclusions PNET is a rare higly malignant soft tissue tumor. The diagnosis of PNET is established by immunohistochemical and ultrastructural studies.
