胰腺囊性肿瘤很少见,作者通过自己的病例,结合文献,认识到既往对胰腺囊性肿瘤的病理分类,把微小囊性腺瘤和粘液性胰腺囊腺瘤—囊腺癌作为同一病理范畴或同一疾病的二个方面是不确切的。微小囊性腺瘤是胰腺囊性肿瘤的一个特殊类型,为良性病变。它起于胰腺中央腺泡细胞,肿瘤为多囊,均匀一致,大小自2mm至2cm,囊壁内衬以胞浆内含有丰富糖元的扁平立方上皮细胞,常伴有“日曝”样钙
Pancreatic cystic tumors are rare, and the authors, through their own cases and literature, recognized the pathological classification of pancreatic cystic tumors in the past, and considered the microcystic adenomas and mucinous pancreatic cystadenoma-cystadenocarcinoma as the same pathological category or The two aspects of the same disease are inaccurate. Microcystic adenoma is a special type of pancreatic cystic tumor and it is a benign lesion. It originates from the central acinar cells of the pancreas. The tumor is polycystic and uniform. The size is from 2mm to 2cm. The cyst wall is lined with flat cuboidal epithelial cells rich in glycogen in the cytoplasm, often accompanied by “day exposure” like calcium.
