胰腺囊性肿瘤包括胰腺囊腺瘤和胰腺囊腺癌,是较少见的肿瘤。自1930年Becourt首次报告以来,至1984年世界文献报告胰腺囊腺瘤只有300多例,囊腺癌100多例。近年来由于影像学诊断的进步,特别是腹部CT、B超的应用,使胰腺疾病的诊断水平有很大提高。但由于对胰腺囊性肿瘤认识不足,往往误诊为假性囊肿,如美国麻省总医院1977～1986年收治的13例胰腺囊性肿瘤中就有8例误诊为假性囊肿,国内也有类似报告。本文重点复习胰腺囊性肿瘤的病理和临床特点,以期提高对本病的认识。一、病理在胰腺囊性疾病中,绝大多数为胰腺囊肿,其内容物为胰腺的分泌物,由无上皮层的纤维壁所包绕,多因炎症或创伤所引起。覆盖上皮细胞的真性囊肿分为 Pancreatic cystic tumors include pancreatic cystadenoma and pancreatic cystadenocarcinoma, and are rare tumors. Since Becourt’s first report in 1930, 1984 world reports reported that there were only 300 cases of pancreatic cystadenoma and more than 100 cases of cystadenocarcinoma. In recent years, due to advances in imaging diagnostics, especially the use of abdominal CT and ultrasound, the diagnosis of pancreatic diseases has been greatly improved. However, due to insufficient understanding of pancreatic cystic tumors, they are often misdiagnosed as pseudocysts. For example, 8 out of 13 cases of pancreatic cystic tumors admitted to the Massachusetts General Hospital from 1977 to 1986 were misdiagnosed as pseudocysts. Similar reports have been reported in China. . This article focuses on the pathological and clinical characteristics of pancreatic cystic tumors in order to raise awareness of this disease. First, pathology In the pancreatic cystic disease, the vast majority of pancreatic cysts, the contents of pancreatic secretions, surrounded by the fibrous wall without epithelial layer, caused by inflammation or trauma. The cysts covered by epithelial cells are divided into
