胰腺实性及囊性肿瘤(SCT)的临床特点及病理学特征已日趋明了,目前已作为一非胰岛细胞起源的独立肿瘤为广大病理及临床医生所认识。作者对该科室过去诊断为非功能性胰岛细胞瘤的12例手术标本重新进行了病理组织学研究,其中包括HE、PAS、Grimelius染色并似Insulin、Glucagon、Somatostatin以及α_1-antitrypsin抗体进行了免疫组织化学研究。符合以下标准者,诊断为SCT:(1)内眼观,肿瘤为结缔组织包膜包绕,中心因变性坏死而形成囊肿,(2)组织学特征:肿瘤细胞呈乳头状增生并以血管为中心形成玫
The clinical features and pathological features of solid and cystic tumors of the pancreas (SCT) have become increasingly clear. They have now been recognized as an independent tumor of non-islet cell origin by most pathologists and clinicians. The authors re-examined the histopathological features of 12 surgical specimens that had been diagnosed as nonfunctional islet cell tumors in the department, including HE, PAS, and Grimelius staining and immunohistochemistry with antibodies against Insulin, Glucagon, Somatostatin, and α_1-antitrypsin. Chemical research. Those who meet the following criteria are diagnosed as SCT: (1) internal eye, tumor is surrounded by connective tissue capsule, cyst is formed at the center due to degeneration and necrosis, (2) histological features: papillary hyperplasia and vessel The center forms a rose
