目的:进一步探讨阑尾类癌的临床、病理及免疫组化特点。方法:复习13例阑尾类癌的临床、病理资料及HE切片,13例均行嗜铬颗粒蛋白A(CgA)、神经元特异性烯醇化酶(NSE)免疫组化标记。结果:12例术前临床误诊为阑尾炎,1例于子宫肌瘤手术时发现。肿块位于阑尾末端10例,体部3例。光镜下癌细胞大小、形状、染色较一致,排列呈巢团状、缎带状、腺泡状、水纹状等。13例CgA及NSE均阳性。结论:阑尾类癌临床缺乏特异性,确诊靠术后病理检查。预后一般良好。
Objective: To further explore the clinical, pathological and immunohistochemical characteristics of appendix carcinoid. Methods: The clinical and pathological data of 13 cases of appendix carcinoid and HE sections were reviewed. Thirteen of them were immunohistochemically labeled with CgA and NSE. Results: 12 cases of preoperative clinical misdiagnosed as appendicitis, and 1 case of uterine fibroids found during surgery. The mass was located in the apical end of 10 cases, 3 cases of body. Light microscope, the size of the cancer cells, shape, staining more consistent arranged in clusters, ribbons, acinar, water stripe and so on. 13 cases of CgA and NSE were positive. Conclusion: Clinical manifestations of appendix carcinoid lack of specificity, confirmed by postoperative pathological examination. The prognosis is generally good.
