胰腺实体-囊性瘤(SCT)是一种好发于青年女性、预后较胰腺癌良好的肿瘤。过去多用光镜诊断,但阳性率较低。近年来,用免疫组化法大大提高了 SCT 的检出率。应用神经特异性烯醇酶(NSE),通过免疫组化法观察对胰腺实体-囊性(乳头状囊性)肿瘤的免疫反应性。结果有两种不同的抗血清出现 NSE 反应性。肿瘤细胞呈嗜酸性,有一个大空泡,核呈卵圆形切迹, Pancreatic solid-cystic neoplasia (SCT) is a good tumor that occurs in young women and has a better prognosis than pancreatic cancer. In the past, light microscopy was used more frequently but the positive rate was lower. In recent years, the use of immunohistochemistry has greatly increased the detection rate of SCT. Using neuron-specific enolase (NSE), immunoreactivity to pancreatic solid-cystic (papillary cystic) tumors was observed by immunohistochemistry. As a result, there were two different antisera that showed NSE reactivity. The tumor cells are eosinophilic with a large vacuole and the nucleus is ovoid
