Mucinous cystadenoma of the appendix

Mucinous neoplasms of the Appendix are rare conditions, usually diagnosed intraoperatively or postoperatively on the pathology report. They have an association with colonic and ovarian neoplasms, and spillage can result in pseudomyxoma peritonei. While appendicectomy is adequate treatment for cystadenomas, cystadenocarcinomas require a right hemicolectomy. Open approach is recommended for the surgical treatment of these lesions.
