It may be of inflammatory or tumoral origin. It may occur as a result of mucoceles, mucosal hyperplasia, mucinous cystadenoma or mucinous cystadenocarcinoma. Mucinous cystadenoma of the appendix is the most common form, although it manifests itself in many different clinical presentations. It is detected in 0.6% of appendectomy specimens. Preoperative diagnosis is difficult, and it is often detected at laparotomy. Despite existing reservations due to the risk of rupture, laparoscopic surgery is gaining acceptance. Although there is no consensus on the choice of surgery, either appendectomy or right hemicolectomy is applied. In this article, we discussed four patients with appendix mucinous cystadenoma where different surgical methods were applied in light of the literature.eninfo:eu-repo/semantics/openAccessMucocele; appendix; cystadenomaArticle10.5152/UCD.2014.23973029799259319042-s2.0-84903998132Q3WOS:000420217400009N/A
