【摘要】 目的:探讨阑尾原发性恶性肿瘤的临床病理及免疫组化特征。方法:对22例阑尾原发性恶性肿瘤进行临床资料回顾及行免疫组化研究。结果:原发性恶性肿瘤22例(类癌19例,腺癌3例),类癌表达内分泌标记阳性,腺癌表达上皮性标记而内分泌标记阴性。结论:阑尾原发性恶性肿瘤少见,临床术前表现为炎症,多由术后病理检查偶尔发现,免疫组化有利于明确诊断。更多还原

【Abstract】 Objective:To investigate the clinicopathological and immunohistochemical features of primary malignant tumor of the appendix. Methods:The clinical data were reviewed; and histopathological and immunohistochemical features were analyzed in 22 cases with primary malignant tumor of the appendix. Results:In 22 cases of primary malignant tumor of the appendix,19 cases were carcinoid and 3 were adenocarcinoma. Immunohistochemistry showed that the carcinoid was positively reacted to the neuroendocrine markers,and the adenocarcinoma was negatively reacted to the neuroendocrine markers. Conclusion:Immunohistochemistry is useful in diagnosis of primary malignant tumor of the appendix,a rare type of cancer.更多还原
