阑尾的粘液性囊腺瘤一般在外科手术时偶而发现。尽管它的发生率较低,约占全部切除阑尾的0.3%,但却为外科医生所熟知。其病因并不清楚,有些人认为它是阑尾近端管腔因纤维化阻塞造成的;另一些人考虑它是阑尾的原发性肿瘤。我们利用组织化学和亚显微结构的技术,研究了9例阑尾粘液性囊腺瘤,其中2例伴有腹膜的假粘液瘤。我们并将 The appendix mucinous cystadenoma is occasionally found during surgery. Although it has a low incidence of about 0.3% of all appendixes, it is well known to surgeons. The etiology is not clear, and some people think it is caused by obstruction of fibrosis in the proximal duct of the appendix; others consider it to be the primary tumor of the appendix. Using histochemical and submicroscopic techniques, we studied 9 cases of appendicular mucinous cystadenoma, of which 2 cases had pseudomyxoma with peritoneum. We will
