Endometriosis causing Invaginated Mucinous Cystadenoma of Appendix: Case Report

Abstract

Mucinous tumors are mainly located in the ovary with a total of 10-15% of all tumors. Among them 80% are benign and borderline tumors and other carcinomas. The extraovarian primary form, is an unusual presentation (most of the time localized on appendix) [1, . Endometriosis, in the other hand, is the extrauterine presence of endometrial glands and stroma. It normally compromises pelvic organs and less frequently other ones, like bowel, affected in 3 to 37%, whilst appendix only in 0.8% according to authors [3, 4, . Even though the clinical presentation is chronic pelvic pain, the appendix is usually asymptomatic [2, . The gold standard for its diagnosis is laparoscopy, which allows direct visualization and subsequent pathologic confirmation of disease and complications . This case report describes a particular presentation of invaginated mucinous cystadenoma tumor of appendix due to endometriosis successfully treated with laparoscopic surgery.
