在胚胎学上阑尾来自大肠。因而大肠的肿瘤样疾病亦可发生在阑尾。本文讨论阑尾良、恶性肿瘤的治疗。 良性肿瘤:阑尾良性肿瘤的发生率为0.2％,有两个主要类型:息肉和腺瘤。息肉与腺瘤的唯一区别是组织学没有不典型的细胞核。腺瘤产生大量粘液形成一个大的香肠形囊性包块(囊腺瘤);粘液积聚在阑尾壁内形成粘液囊肿。如果囊腺瘤和粘液囊肿破裂,其内容物常积聚在右髂凹内(局限性腹膜腔假性 In embryology, the appendix comes from the large intestine. Therefore, the tumor-like disease of the large intestine can also occur in the appendix. This article discusses the treatment of appendiceal benign and malignant tumors. Benign tumors: The incidence of benign appendix tumors is 0.2%. There are two main types: polyps and adenomas. The only difference between polyps and adenomas is that histology does not have atypical nuclei. The adenoma produces a large amount of mucus to form a large sausage-shaped cystic mass (cystic adenoma); mucus accumulates in the wall of the appendix to form a mucinous cyst. If the cystadenoma and mucous cyst rupture, their contents often accumulate in the right atlas (localized peritoneal pseudo
